The Coleoptera of Florida. 

By E. A. Schwarz.* 

(Bead before the American Philosophical Society, Feb. 1, 1878.) 

The following list is founded upon material collected during two expe- 
ditions to Florida. In the spring of 1875 collections were made at Haul- 
over near the northern end of Indian River from February 23d to March 
20th, at Ft. Oapron, on the same lagoon about a hundred miles south of 
Haulov^. r, from March 26th to April 28th, at Enterprise on the upper St. 
Johns River from May 7th to 28th, at Cedar Keys, on the gulf coast, from 
June 2d to 9th. In the following year collections were made at Tampa 
from March 24th to April 30th, and again at Enterprise from May 15th to 
June 27th. 

On both trips smaller collections were made at various points : Fernan- 
dina April 16th, Palatka February 13th, Sand Point on the Indian River 
February 19th to 22d, Lake Harney on the upper St. Johns River in the 
beginning of May, at Baldwin on the Jacksonville and Mobile R. R. on 
June 1st and June 10th, Lake Ashby in Volusia County and New Smyrna 
in the beginning of June. A number of interesting species were also ob- 
tained on the journey across the peninsula from Tampa to Enterprise dur- 
ing the first half of May. 

As the localities Avhere the most extensive collections were made differ 
greatly in character, and as no points in north- western Florida, nor at the 
southern extremity of the peninsula were visited, I must abstain from 
drawing any conclusions concerning the local distribution of Coleoptera in 
Florida. The sanely plains at Haulover, covered with scrub-oak and saw- 
palmetto, were not found elsewhere ; the ocean and lagoon beaches of the 
eastern shore, especially at Capron, are rich in peculiar forms, and as the 
Gulf Stream here flows only six or eight miles off the coast, it is quite 
possible that many of these species are direct importations brought in the 
West Indian seeds and drift-wood constantly being thrown upon this low 
and sandy coast. 

The Coleoptera from Enterprise represent the fauna of the " hammocks, " 
a term applied in Florida to the dense hard- wood and palmetto forests, as 
distinguished from the open and sandy pine lands or cypress swamps. At 
Tampa special attention was paid to the fauna of the pine forests. In all 
districts covered with pine w T oods occur depressions, which in the dry sea- 
son become swampy meadows, with a fauna remarkably rich in species 
and in specimens, and nearly identical in character throughout the State. 

Notwithstanding the very uniform temperature during the entire year, the 
dry season, which corresponds with the winter months, causes a disappear- 
ance of insects in Florida almost as complete as in the north ; in the 
beginning of March they appear suddenly with the first leaves of the oak,

but there is no spring flight of Coleoptera. The beginning of the rainy 
season about the end of May brings out the full summer fauna. 

Though far from complete, the following enumeration of species is 
judged sufficiently extensive to give a tolerably clear idea of the character 
of the Floridian fauna. 

I desire to express my indebtedness to Dr. LeConte, without whose aid 
in the determination of species, this list could not have been prepared. 

The following abbreviations for localities are used in the List of Species.

Descriptions of New Species. 

Br E. A. Sciiwaez. 

l.'L.ebia rhodopus, n. sp. — Head and thorax greenish or bluish 
black, subopaque ; the former large, wider than the thorax, finely alula - 
ceous, sparsely and obsoletely punctulate ; antennae more than half the 
length of the body, outer joints stout, joint 3 and base of joint 4 testaceous ; 
palpi black. Thorax small, transverse, on the sides very little rounded and 
subsinuate before the hind angles, which are rectangular ; side margin less 
broadly reflexed than in L. vir^dis ; finety alutaceous, indistinctly trans- 
versely rugose or obsoletely punctulate. Elytra blue or greenish blue, 
shining, very finely alutaceous, strias finer and more obsolete than in L. 
viridis, interstices subconvex. Beneath bluish black, legs, including the 
coxae, bright rufo-testaceous, tarsi blackish, claws pectinate. Length 4.5 
mm. ; .17-18 inch. 

Allied to L. viridis and pumila ; from the former distin- 
guished by its larger head, which as well as the thorax,- is 
hardly shining, and by the color of antennae and legs ; from 
the latter by its larger size and the coloration of the upper 
side and of the legs; from either species by the long and 
stout antennae. 

Two specimens from Tampa, found in April on the blos- 
soms of Chamserops serrulata. 

2. Apenes angustata, n. sp. — Shining, head and thorax metallic 
green, elytra dark coppery ; beneath black, antenna?, palpi and legs testa- 
ceous. Head a little narrower than the" thorax, longitudinally strigose, 



L878.J °°5 [Schwarz. 

with some scattered punctures, clypeus alutaceous, minutely and sparsely 
punctulate. Thorax in front but little wider than long, at the sides less 
rounded and less narrowed behind than in A. lucidula ; hind angles indi- 
cated by an interruption of the reflexed margin, transversely rugulose and 
sparsely punctulate, near the front margin more evidently punctate, punc- 
tures sometimes confluent in longitudinal rugosities. Elytra of a dark 
coppery color with an oblong yellow spot at the base of the 6th interval, 
finely but deeply striate, stride distinctly punctulate, interstices flat, aluta- 
ceous, sparsely and obsoletely punctured. Length 9.25 mm. ; .37 inch. 

Of the same size as A. lucidula, but narrower and with a 
different form of the thorax ; the sculpture of head and 
thorax is finer, the elytra are darker colored with the scat- 
tered punctures on the interstices less evident. 

Enterprise ; three specimens, apparently females. 

CYCLO^fOTUM. 

The four North American species before me may be dis- 
tinguished by the following table : 

I. Antennae with more or less solid club ; presternum" carinated in front, 
prolonged behind between the coxa? and almost reaching the meso- 
sternum ; first ventral segment carinate ; elytra with distinctly im- 
pressed sutural striae at apex : 

Antennal club solid, presternum very short in front of the coxae : 
metasternum in the middle slightly but abruptly raised in an ob- 
long shining plate, which is narrowed in front. Size small, rows 
of punctures on the elytra very obsolete palmarum. 

Antennal club less solid, presternum moderately long in front of 
the coxae, metasternum with an oblong, not elevated, not pubes- 
cent, opaque spot. Size large, elytra with regular rows of punc- 
tures cacti. 

II. Antennas with a loosely jointed club of three joints, presternum feebly 
prolonged between the coxse ; metasternum strongly longitudinally 
carinated, carina shining, more or less punctulate, but not sharply limited 
laterally ; first ventral segment not carinated ; elytra without sutural 
stria. 

Larger, rounded-oval, elytra moderately densely punctulate, legs pice- 
ous black, tibiae distinctly punctulate estriatum. 

Smaller, rounded, almost hemispherical, elytra less densely punctu- 
late, legs stouter, piceous red, tibiae smooth semiglobosum. 

3. Cycloiiotum palmarum, n. sp. — Rounded-oval, convex, 
above black, shining, anterior part of head, sides of thorax and tip of ely - 
tra sometimes red, beneath red, metasternum darker in the middle, anten- 
nae, mouth and legs bright rufo-testaceous. Head very finely aciculate and 



Schwarz.] dOO [Feb. 1, 

obsoletely remotely punctulate, antennae with the first joint elongated, but 
much less so than in C. cacti, 2d joint as thick as the first, longer than 
wide, 3d much narrower but also longer than wide, 4th very small sub- 
transverse, 5th and 6th very small strongly transverse ; the three last joints 
are absorbed in a large, elongate-oval, solid annulated club, which is al- 
most as long as the first joint and less compressed than in C. cacti. Mentum 
transverse, flat, subopaque, testaceous, not visibly punctured, broadly emar- 
ginate in front. Prothorax sculptured a,s the head, broadly emarginate in 
front, sides feebly rounded, base straight, anterior angles distinct, not' 
rounded, hind angles obtuse. Scutellum shining, very finely sparsely 
punctulate. Elytra shining, not densely, finely punctured, with traces of 
rows of stronger punctures at the apex near the side margin ; sutural stria 
finely impressed ami reaching almost to the middle. Prosternum in front 
of the coxse veiy short, linear, carina more prominent in front, intercoxal 
process long, almost reaching the mesosternum. Carina of mesosternum 
with the free angle almost rectangular, not mucronate. Metasternum on 
each side opaque, not visibly punctured, in the middle slightly but abruptly 
elevated in an oblong, shining plate, which is somewhat narrowed in front 
and finely remotely punctulate. Abdomen opaque, first segment carinated 
in the middle. Legs stout, femora punctulate, tibia? smooth. Length 1.75 
mm. ; .07 inch. 

Enterprise; live specimens, found in May and June, on cut 
down palmetto trees feeding on the fermenting juice. 

C. semiglobosam Zimm. (Trans. Am. Ent. Soc. 1869, p. 250), 
is in my opinion well distinguished from C. estriatam. It 
is always smaller, shorter and more convex, the front 
margin of thorax distinctly produced in the middle, the 
punctation of head and thorax is much finer, that of the 
elytra less dense, fine in the scutellar region, stronger at 
apex and at the sides ; the legs are stouter and less dark 
colored, the tibise smooth. 

4. Sacium mollinum, n.sp. — Elongate-oval, shining, above pice- 
ous, thorax semicircular with the apex and sides pale, diaphanous anteri- 
orly, finely and moderately densely punctulate. Elytra minutely sparsely 
punctulate, pubescent, a humeral spot, a curved fascia at the apical third, 
and the side margin yellowish -testaceous. Beneath piceo-testaceous, ab- 
domen and legs pale, metasternum densely punctulate. The yellow side 
margin is connected with the humeral spot and with the fascia ; the latter 
is sometimes abbreviated at the sides or reduced to a spot on the disc. 
Length 1 mm, ; .04-. 05 inch. 

Tampa and Enterprise, many specimens ; abundant on Pinus 
palustris in April and June. Shorter and more regularly 
oval than the other species and of different coloration. 



1878.] &D i [Schwarz. 

5. Sari ii m spleiidens, n. sp. — Elongate-elliptical, very shining, 
thorax semicircular, reddish with an indefinite dark spot in front of mid- 
dle, apex and sides pale, very finely sparsely punctulate. Elytra piceous- 
black with an indistinct reddish basal spot ' inside of the humerus and a 
common, broad, testaceous fascia behind the middle, exceedingly finely re- 
motely punctulate, pubescence only visible under a very high power. Un- 
derside reddish-brown, shining, hardly visibly punctulate, abdomen paler 
at apex, legs yellowish-testaceous. Length 7 mm. ; .03-. 04 inch 

Tampa ; many specimens beaten from dead leaves of Pinus 
palustris in April. Varies with, the fascia interrupted by 
the suture, or not reaching the side margin. The apparently 
unpubescent and very shining elytra with the very fine punc- 
tuation will easily distinguish this species. 

6. Scydmaemis divisus, n. sp. — Fusiform, shining ; head and tho- 
rax brown, impunctate, with coarse, erect, nioderatety long, brownish 
pubescence. Head not immersed in the thorax, with a thick brush of 
hairs each side behind the eyes ; antennae red, stout, longer than head and 
thorax, intermediate joints as long as wide, club 4-jointed, 8th joint globu- 
lar twice as large as the preceding, joints 9 and 10 subtransverse, each very 
little larger than the 8th, terminal joint oval, shorter than the two preceding 
together ; maxillary palpi with the penultimate joint slender, clavate, last 
joint not visible. Thorax trapezoid, very little longer than wide at base, 
smooth, transverse basal impression feeble, interrupted at the middle. 
Elytra not forming an angle with the thorax, with sparse, long, erect, 
grayish pubesence, red, evidently punctate anteriorly and smooth behind 
the middle ; punctate part divided in an inner and outer portion by a broad 
smooth humeral band, inner portion more finely and sparsely, outer por- 
tion more coarsely and densely punctured ; humeral callus moderately 
elevated ; two distinct basal foveae each side of almost equal size ; suture 
not elevated. Beneath piceous, abdomen pale at tip, legs red, femora mode- 
rately clavate. Length 1.15 mm. ; 4.5 inch. 

Enterprise ; two specimens. Belongs in the group of S. 
capUlosulus and is easily distinguished by the peculiar sculp- 
ture of the elytra. 

7. Languria margin ipennis, n. sp. — Red ; head, and small 
rounded discoidal spot on the thorax, scutellum, outer half of femora, the 
larger part of the tibiae and the tarsi blackish-green; antennae, metasternum, 
with the exception of the front margin, and the last ventral segment black; 
elytra greenish-blue or blue, margin and epipleurae red. Head alutaceous, 
distinctly not densely punctured, antennae with joints 3-6 slender, 7-11 
forming an abrupt club, joints 7-10 produced within. Thorax longer 
than wide, finely aciculate and distinctly not densely punctured, on the 
sides very little rounded and slightly sinuate before the hind angles ; the 



Schwarz.] ddO [Feb. 1, 

more or less rounded spot in the centre and occupies usually the fourth 
part of the length of the thorax, but is in some specimens reduced in size. 
Elytra shining, strongly striate-punctate, punctures finer towards the apex, 
interstices flat, finely alutaceous, obsoletely remotely punctulate ; the red 
color is usually confined to the thickened margin and to the epipleurse , but 
in two specimens the last interstice also is indistinctly red in the middle. 
Presternum sparsely punctured, almost smooth t in front, mesosternum 
coarsely punctured, metasternum almost smooth, abdomen finely, remotely 
punctulate. The red and green colors on the tibiae are not sharply sepa- 
rated ; the base and the upper edge, however, are always dark and the 
largest part of the lower edge always red. Length 7-9 mm. ; .28-. 35 inch. 

Ft. Capron, Tampa, and Enterprise ; six specimens. This 
species resembles in form L. tcedata, it is, however, a little 
more elongate with the thorax longer. 

8. Tomariis liirtellus, n. sp. — Oblong-oval, convex, shining, fus- 
co-testaceous. Head and thorax finely, sparsely punctulate, sparsely pubes- 
cent ; antennae less slender than in T. pulchellus. Thorax twice as wide 
as long, on the sides snbsinuate before and slightly undulate behind the 
middle, base sinuated each side, basal impressions deep. Elytra with 
sparse, suberect, grayish pubescence, and with some scattered long erect 
hairs, strongly irregularly punctate in front, punctures becoming finer 
and obsolete towards the apex ; an indefinite, often abbreviated, fascia at 
the middle and another on the apical third black. Beneath finely, sparsely 
pubescent, pro- and metasternum evidently punctulate ; legs pale. Length 
1.25-1.5 mm ; .05-. 06 inch. 

Smaller and shorter than T. pulchellus and easily distin- 
guished by its more evident pubescence and stronger punc- 
tuation on the elytra. The pubescence of T. hirtellus and 
the form of the thorax, whose side margin has the tendency 
to become serrulate, bring the genus lomarus still nearer to 
Paramecosoma. 

9. lift tlirop us pictus, n. sp. — Opaque, head and thorax ferrugineo- 
testaceous, the former densely rugosely punctulate, emarginate in front, 
antennae ferrugineous, second joint and the club blackish, joints 3 — 8 very 
small, together hardly as long as the club. Thorax transverse, side mar- 
gins undulate, apical margin and base straight, anterior angles almost 
rectangular, hind angles prominent ; finely and densely rugosely punctu- 
late, without any trace of impressions, lateral lines feeble. Scutellum 
small, transverse. Elytra much less elongate than in L. vernalis, fusco- 
testaceous, finely punctate-striate, with numerous rows of exceedingly 
short, rigid, whitish hairs ; a circuinscutellar cloud and a common fascia, 
concave and dentate anteriorly, blackish. This fascia is formed of three 
indefinite spots on each elytron, the first at the suture a little behind the

middle, the second, oblong, in front and outside of the first, the third at 
the side margin. Metasternum and abdomen piceous, finely sparsely 
punctulate ; legs pale. Length .05 inch ; 1.25 mm. 

Smaller and especially shorter than L. vernalis and dis- 
tinct by the disc of the thorax without impressions, by the 
sculpture and pubescence of the elytra and by the color. 

Haulover Canal, Yolusia County ; four specimens found 
under bark of a dead Quercus virens. 

10. Laemophloeiis Cliamaeropis., n. sp. — Less elongate, de- 
pressed, glabrous, shining, bright rufo-testaceous, elytra pale ochreous. 
Head large, transverse, flat, not impressed on the disc and without median 
line, finely and sparsely punctulate, marginal line close to the margin in 
front and at the sides, base not margined ; antennas with distinct 3-jointed 
club ; labrum large, transverse, truncate in front. Thorax finely, sparsely 
punctulate, with a single lateral line joining the basal marginal line and 
with an impressed puncture of moderate size each side in the middle out- 
side of the lateral line ; anterior angles not prominent in either sex. Scutel- 
lum transverse, triangular. Elytra at base very little wider than the tho- 
rax, slightly dilated behind the humeri, which are obtuse but not rounded ; 
each elytron with six fine strise : the humeral stria more distinct and im- 
punctate, 5th stria also more distinct, obsoletely punctulate, the inner striae 
less distinct and feebly punctulate, sutural strise at apex more impressed 
than in front. Interstices flat impunctate. Head beneath, pro- and meso- 
sternum impunctate, metasternum and abdomen finely sparsely, last ven- 
tral segment more densely punctulate. Length 1.5-2 mm. ; .06-. 08 inch. 

cT Head wider than the thorax, front produced, emargi- 
nate at middle, distinctly sinuate each side, with the teeth 
long and acuminate ; antennae slender, more than half the 
length of the body, with all the joints longer than wide. 
Thorax strongly transverse, sides oblique, convergent towards 
the base and subsinuate before the hind angles, which are 
obtuse; lateral line oblique; elytra as long as head and 
thorax together.' 

9 Head as wide as the thorax, front produced, emarginate 
in middle, hardly sinuate at the sides, teeth much less prom- 
inent ; antennae less slender, outer joints as long as wide. 
Thorax less transverse, sides sub-parallel, slightly arcuate 
and sinuate before the hind angles, which are rectangular, 
lateral line straight ; elytra a little longer than head and 
thorax together.

11. JVemicelus margiiiipemiis Lee. — The two sexes differ from 
each other most remarkably and might be easily mistaken for two distinct 
species. The form described by LeConte (Proc. Ac. Nat. Sc. 1854, p. 79), 
I take to be the tf. The female differs chiefly by the following characters : 
Less elongate, opaque above, color of upper and underside darker. Head 
densely rugosely punctulate with an obtuse tooth behind the eyes, eyes 
smaller, less elongate and less oblique, more convex ; antennae with the 
first joint only one-half longer than wide, shorter than the two following to- 
gether. Thorax hardly longer than wide anteriorly, more dilated in front, 
not emarginate at apex, apical edge thickened, base much less lobed in 
the middle, surface densely rugosely punctulate. Elytra almost entirely 
covering the abdomen, less truncate at apex, distinctly pubescent, densely 
punctulate, striae less evident. Presternum shining, punctate, process be- 
tween the front coxae hardly visible, propleurae opaque, sculptured as the 
thorax; mesosternum much smaller, less broadly rounded in front, dilated 
behind, shining punctate ; metasternum and abdomen opaque, the latter 
less elongate, last segment not longer than the preceding with a large shal- 
low impression. Hind tarsi 4-jointed as in the male. 

The genus Nemicelns was first described by Dr. LeConte, 
and is certainly distinct from Hemipeplus. 

12. Xeiniceliis microplitlia limis, $ n.sp. — Linear, pale, yellow- 
testaceous. Head quadrate, subconvex, behind the eyes straight, then 
suddenly narrowed and forming a short neck, somewhat shining, sparsely 
and obsoletely rugose ; eyes small, round, convex, very coarsely granula- 
ted, mandibles deeply emarginate and black at tip ; antennas a little longer 
than head and thorax, first joint stout one-half longer than Avide, shorter 
than the two following together, joint 2 globular, the following 4 joints as 
long as wide, equal, 7 and 8 a little larger than the preceding, the three 
last joints abruptly larger, 9 and 10 hardly transverse, terminal joint oval 
acuminate. Thorax but little longer than wide anteriorly, feebly and 
broadly emarginate in front, sides oblique, convergent towards the base, 
subsinuate anteriorly and broadly sinuate before the hind angles ; base al- 
most straight, not lobed, apical edge thickened, anterior angles obtuse; 
rounded at tip, posterior angles obtuse ; surface somewhat shining, indis- 
tinctly, rugosely punctulate with a faint trace of an impressed median line, 
basal impressions large and deep. Scutellum opaque, subquadrate and a little 
broader behind, apical side rounded. Elytra almost covering the abdomen, 
subopaque, paler than the head and thorax, darker at the sides and with a 
short dark line on each elytron near the suture at the apical fourth, densely 
and equally rugosely punctulate with hardly any trace of striae. Pro- and 
mesosternum shining, sparsely punctulate, propleurae opaque, sculptured 
as the thorax, front coxae very narrowly separated, metasternum and abdo- 
men subopaque densely and finely punctulate, last ventral segment hardly 
longer than the preceding with a round impression, occupying nearly the 
whole surface. Length 3.25 mm. ; .13 inch. 

tf Unknown to me. 



1878.] °^1 [Schwarz. 

A single specimen from Enterprise, found in May, attracted 
by the light, is before me, another specimen from Tampa is 
in the cabinet of Dr. LeConte. Smaller and narrower than 
the smallest females of N. marginipennis and very distinct, 
especially by the form of the head and by the small, round 
eyes. 

13. Pliilotliermus puberiilus, n. sp. — Elongate-elliptical, trans- 
versely convex, dark chestnut-colored, shining, above with distinct, fine, 
erect pubescence and with some longer hairs at the sides. Head sparsely 
punctured, antennae shorter than in Ph. glabriculus, apparently 10-jointed, 
joints 2 and 3 slender, the following six joints small, 7-9 strongly trans- 
verse, joints 10 and 11 forming a solid club as in Cerylon. Thorax less 
transverse and less strongly margined than in Ph. glabriculus, rounded on 
the sides, moderately sparsely punctured. Scutellum transverse, shining, 
with a few punctures. Elytra strongly striate-punctate, interstices finely, 
sparsely punctulate. Presternum and propleurse distinctly, not densely, 
metasternum and first ventral segment in the middle finely and sparsely, 
at the sides very coarsely punctured, segment 2-4 each with two trans-' 
verse rows of strong punctures, last segment more finely punctulate ; legs 
testaceous. Length 2 mm. ; .075 inch. 

Abundant in Florida under old bark of Pinus palustris. 
Smaller, narrower and more convex transversely than Ph. 
glabriculus, with the sculpture above and beneath stronger and 
at once distinguished b}^ the much more evident pubescence 
and by the form of the antennal club. By this last charac- 
ter Ph. puberulus forms a passage to Cerylon. Sexual charac- 
ters are not evident ; some specimens have the sides of thorax 
less rounded ; these are probably the males. 

14. Olibrus priiiceps, n. sp — .Rounded-oval, pale rufo-testaceous, 
thorax with a large brownish discoidal spot. Elytra black each with a 
large, oval, bright orange-colored spot at the suture before the middle, 
outer half of the basal margin and the lateral margin narrowly, apex 
broader yellow ; very finely striate, striae minutely and remotely punctu- 
late, interstices obsoletely sparsely punctulate, punctures more distinct 
near the lateral margin. The sutural stria alone is deeper impressed ; mes- 
osternum not protuberant. Length 2.5 mm.; .10 inch. 

One specimen in the collection of Mr. H. G-. Hubbard 
from New Smyrna ; another specimen found by me at En- 
terprise in May is in the cabinet of Dr. LeConte. A very 
striking species by its color, belonging in the group of 0. 
apicalis.

15. Bracliyacantlia querceti; n. sp. — Rounded, convex, shining, 
black ; head and thorax finely not densely, elytra somewhat more strongly 
punctured. Each elytron with a large, transverse humeral spot, which is 
obliquely truncate inside and leaves a very narrow basal margin black and 
with a smaller, rounded-oval spot at the outer apical angle not touching 
the margin, orange-red. Side pieces of metasternum and sides of abdo- 
men densely punctured, propleurae and legs yellow, femora infuscate at 
base. Length 2-2.75 mm. ; .08-.11 inch. 

(^ Head, front margin of thorax narrowly, anterior angles and side 
margins more broadly, epimera of mesosternum entirely whitish-yellow. 

9 Head black, or piceous in front, thorax black or with the front mar- 
gin and front angles narrowly piceous-testaceous, epimera black or piceous. 

var. a Humeral spot small and narrow. 

var. fj Humeral spot interrupted at middle. 

Widely distributed in Florida ; abundant on oak shrubs. 

16. Hyperaspis paluclicola, n. sp. — Oblong-oval, less convex, 
black ; head subopaque, finely alutaceous, obsoletely sparsely punctulate 
thorax opaque, sides yellow, sculptured as the head. Elytra shining, dis- 
tinctly moderately densely punctate, an oval discoidal spot, the side mar- 
gin and the apex yellow. The yellow side margin is throughout of equal 
width, following the undulation of the side margin of the elytra ; at the apex 
it turns inwards and becomes broader, but does not reach the suture. 
Mouth, antennas, epipleura?, legs, sides and apex of abdomen, yellow, 
Length 1.35-2.25 mm. ; .07-. 09 inch. 

<$ Head and front margin of thorax yellow. 

Very common in Florida on swampy meadows in the 
Pine lands. Resembles in coloration certain varieties of H> 
undulata, but it is longer, less convex and also a little 
smaller, with the thorax opaque and less distinctly punctu- 
late ; the yellow side margin is always of equal width and 
never broken into spots.

above glabrous and only at the sides fringed with a row of longer hairs. 
Head piceous with greenish reflection, transversely convex behind, flat- 
tened in front, moderately sparsely punctate and not rugose, vertex more

pnhescence, legs testaceous, femora infuscate ; front tibiae not dentate, the 
apical tooth being a mere prolongation of the outer apical angle in the axis 
of the tibia?, upper edge therefore almost straight, only very slightly sinu- 
ate at the base of the apical process, outer side neither carinate nor sulcate, 
smooth with exception of a row of punctures along the upper edge ; first 
four tarsal joints short, claws strongly incurved at base Length 4-4.5 
mm.; .16-. 18 inch. 

Three specimens are before me which I found on oak 
shrubs on the sand hills east of Lake Altapopka in May. 
Easily distinguished from our two other species by its 
smaller size, more regularly oval, convex form, by the glab- 
rous upper surface, by the sculpture of head, thorax and 
elytra and by the formation of the front tibiae. 

18. Taplirocerus puncticollis, n. sp. — Elongate, above black- 
ish-blue, or black with faint seneous tinge, shining. Head less strongly 
excavate, very finely alutaceous, distinctly, moderately sparsely punctate, 
punctures deeper than in T. gracilis. Thorax transverse, narrowed in front 
when viewed from above, sides sinuate before the hind angles, which are 
rectangular, base strongly lobed in the middle, lobe broadly emarginate ; 
surface uneven with a distinct carina in front of the hind angles, very 
finely alutaceous, coarsely unequally punctured, each puncture bearing a 
very short scale-like hair. Scutellum transverse, shining. Elytra im- 
pressed at base, impressions on the disc not obvious, serrate at the outer 
apical angle ; anteriorly moderately strongly striate-punctate, punctures 
obsolete towards the apex, each with a very fine, short hair, interstices on 
the disc unequal ; the stria? therefore appear subgeminate ; humeral carina 
broadty interrupted at middle. Beneath bluish-black or black, metasternum 
coarsely punctured ; abdomen with sparse shallow punctures, last segment 
with a deep, semicircular marginal sulcus. Length 5 mm. ; .20 inch. 

Enterprise and Cedar Keys ; two specimens. More elon- 
gate than T. gracilis and distinguished by the deeper punc- 
tuation of head, thorax and metasternum and by the elytra 
less even, without patches of pubescence ; from T. agriloides 
it differs chiefly by the form of the thorax, which in the lat- 
ter species is not narrowed in front when viewed from above. 

19. Bracliys fascifera, n. sp. — Similar to B. ovata, but shorter, 
broader in front and more attenuate behind, and easily distinguished by 
the broad white fascia on the elytra and by the formation of the prosternum. 
Head and thorax as in B. ovata, the former less strongly excavated. Ely- 
tra striate-punctate, punctures finer and obsolete towards the apex, ante- 
riorly with irregular lines and patches of fulvous and whitish pubescence . 



Schwarz.] t>()4 ^ eb> 1? 

behind the middle with a broad fascia of dense whitish pubescence, with 
only a few fulvous hairs intermixed ; behind this with two other undulated 
fasciae composed of fulvous hairs bordered anteriorly with white ; humeral 
and marginal carina as in B. ovata. Fissure of presternum not reaching 
the hind margin, but leaving a comparatively broad margin intact, apex of 
metasternum in the middle suddenly and deeply emarginate. Last ventral 
segment with the usual marginal sulcus, not emarginate in the male; broadly 
rounded in the $ , less broadly in the ^ ; anus very finely pectinate. 
Length 4.5-5 mm. ; .18-. 20 inch. 

Widely distributed in Florida and not rare ; lives on 
Quercus virens. In B. ovata and tesselata the undivided por- 
tion of the prosternum is very narrow and the metasternum 
is broadly triangularly emarginate in front. 

20. Pachyscelus caeruleus, n. sp. — Short ovate, black, head and 
thorax bluish-black or black with aBiieous tinge, scutellum and elytra bright 
blue, shining. Head deeply channeled, alutaceous, obsoletely punctulate, 
thorax without lateral depression and with sparse shallow punctures almost 
obliterated on the disc, more obvious at the sides, finely alutaceous at the 
sides. Elytra with a deep impression at the sides before the middle, and 
with another obsolete one near the suture behind the middle, plainly punc- 
tured, with traces of regular rows on the disc Length 2-3 mm.; .08-.12 
inch. 

<$ Last ventral segment with an oblong impression at apex, apical mar- 
gin produced in the middle into two prominent processes each of which 
terminates in four small teeth. 

9 Last ventral segment not impressed, apical margin produced in the 
middle in an acute point. 

Very abundant everywhere in Florida. In form and size 
this species resembles P. laevigatas; the elytra are however 
less triangular and more rounded at the sides ; it differs also 
by its color and by the thorax not being impressed at the 
sides. Very probably there will also be a difference in the 
sexual characters of the males but I have not seen the cT of 
P. laevigatas. In P. purpureas the last ventral segment of 
the cT has a similar impression but the two processes are 
more separated from each other and each terminates in three 
teeth. 

21. Teinnopsoplius iinpressus n. sp. — Black, shining ; head pic- 
eous or piceous-red, finely alutaceous and sparsely punctulate with a fine 
median line on the vertex, antenna? two-thirds as long the body, piceous- 
red at base. Thorax almost longer than wide in front, strongly convex,

transversely depressed before the base, strongly rounded at apex and pro- 
duced in the middle, at the sides rounded anteriorly, towards the base 
narrowed and subsinuate; base distinctly emarginate and finely margined; 
surface piceous or piceous-red, smooth in the middle, finely alutaceous and 
obsoletely punctulate towards the sides. Scutellum semicircular, opaque. 
Elytra elongate-oval, widened behind, basal third strongly depressed and 
transversely impressed, apical two-thirds ventricose, convex, sides sinuate 
in front of middle ; color black with a large yellow marginal spot behind 
the humerus, base frequently piceous-red ; depressed part coarsely, densely, 
ventricose part sparsely punctured, each puncture bearing a short whitish 
hair. Legs piceous-black or piceous-red, hind tibiae slender, slightly 
curved. Length 2-2.5 mm. ; .08-. 10 inch. 

tf Sides of head in front of eyes straight, convergent anteriorly, anten- 
nae with the first joint formed as in the tf of T. Mmaculatus, elytra 
more elongate, less ventricose behind. 

9 Sides of head rounded anteriorly, first joint of antennae not dilated, 
a little longer than the two following together, elytra strongly convex and 
ventricose behind. 

Eight specimens are before me, found on the meadows 
north of Lake Ashby, Yolusia county, in June. 

The yellow humeral spot extends sometimes so as to nearly 
reach the suture. 

Easily known from T. bimaculatus by the form of the elytra.

strongly transverse ; joints 5 and 7 a little larger, strongly transverse, and 
produced inwards ; last three joints strongly compressed, the 9th twice as 
long as wide, as long as 2-8 together, and as long as 10 and 11 together, 
outer margin straight, inner margin convex, inner front angle somewhat 
produced, inner basal angle rounded ; joint 10 longer than wide, truncate 
at tip, outer margin straight, inner margin strongly sinuate at the basal 
half; joint 11 closely applied to the 10th, as long as wide, rounded at tip ; 
maxillary palpi with the last joint large, triangular. Thorax anteriorly a 
little wider than long in the middle, very convex transversely, apical 
margin slightly produced at middle, and feebly sinuate each side, sides 
straight, strongly convergent in front, base lobed at middle, feebly sinuate 
each side; front angles strongly deflexed, acute, but not prominent, hind 
angles obtuse, rounded ; finely, sparsely punctulate, more densely towards 
the anterior angles, and with an impressed marginal line at the sides. Scu-

hardly widened externally, evidently punctate. First ventral segment 
finely and sparsely punctulate, excavated parts opaque, rugose, second seg- 
ment longer than the first, very finely and remotely punctulate ; third and 
fourth segments of equal length, each shorter than the second, and similarly 
punctulate, punctures denser and stronger at the sides; last segment as long

tured ; labrum trilobed, middle lobe triangular, lateral lobes broad, trun- 
cate. Thorax transverse, convex, at apex a little produced, at the sides 
strongly rounded and margined; anterior angles auriculate, posterior angles 
dentiform, prominent ; brownish-red with three indefinite spots often con- 
fluent in an M-like mark; coarsely, not densely punctured, on the disc 
finery, at the sides more distinctly alutaceous. Scutellum piceous, smooth, 
or with a few punctures. Elytra parallel at the sides, broadly rounded at 
apex, strongly, regularly striate-punctate, punctures fine at apex ; inter-

little behind the middle. EpipleuraB of thorax black, smooth; metasternum 
piceous, shining, sparsely rugose; abdomen reddish-testaceous, sub-opaque, 
alutaceous and obsoletely punctate ; legs pale. Length 3.5-4.25 mm. ; .14 
-.17 inch. 

Enterprise, many specimens found in June, mostly on 
Quercns virens. This species resembles very much certain 
varieties of Paria sexnotata. 

24. Chrysomela Ceplialaiitlii ? n.sp.— Oval convex; head opaque; 
brown, almost smooth, maxillary palpi with the last joint a little longer 
than in C.similis, but not dilated. Thorax short, emarginate at apex, straight

the suture not abbreviated, but very little narrower at apex than in 
front and including two regular strise of moderately coarse punctures; the 
second and third abbreviated at base and apex, the former limited each side 
by a regular stria of punctures and including two short irregular striae be- 
hind the middle with a few punctures in front; the outer vitta is margined 
interiorly with a stria of punctures and includes two long almost regular 
striae ; the outer marginal stria is broadly interrupted at middle ; the yellow 
parts are impunctate with the exception of a humeral line of very fine 
punctures. Underside, including the epipleurae, brown with scattered 
moderately fine punctures ; legs very coarsely punctured, claw joint not 
dentate, claws stout, distant. Length 6-7.25 mm.; .24-. 29 inch. 

Ft. Capron and Lake Harney, two specimens ; also found 
at Tampa; lives on the Button Bush. Belongs to Calli- 
grapha Er. and is to be placed near C. similis, from which 
it differs by its more elongate form, by the straight side 
margin and less punctured disc of the thorax, by the regular 
vittse and sculpture of the elytra and by the coarsely punc- 
tured legs. 

25. Systena pallipes, n. sp. — Elongate-elliptical, convex, shining, 
black; head and thorax often reddish -brown, base of antennae and legs pale 
testaceous. Head carinate in front, impressed median line fine, smooth

smooth, shining. Elytra elongate, very little broader at base than the 
thorax, humeri rounded, shining, evidently not densely punctate, with 
traces of an impressed sutural line. Length 3-4 mm.; .12-.16 inch. 

Many specimens from different parts of Florida, abundant 
on the swampy meadows in May and June. More elongate, 
narrower and more convex than S. frontalis, with the elytra 
narrower at base, and easily distinguished by its pale legs. 

26. Epitrix Ibrevis, n. sp. — Short-ovate, black, shining, antennae, 
mouth and legs red, posterior femora infuscate. Head impunctate ; thorax 
shining, more finely punctulate than in E. cucumeris, basal impression very

tured line, lateral marginal line impunctate, medial line very fine, side 
pieces opaque, impunctate. First and second ventral segment shining,

Crotch, Proc. Acad. Nat, Se. Pliila., 1873, 74. 

Sumter County, four specimens. Distinct by the form of 
the body, and by the characters of the underside mentioned 
above. 

28. Cliaetocnema quadricollis^ n. sp. — Ovate, less convex, 
shining, above aeneous, head and thorax often brassy ; antennae and legs 
bright testaceous-red, hind femora more or less infuscate. Head prominent 
oblique, deeply transversely impressed in front, not very wide between

striate, BCUtellar stria not reaching the middle, interstices smooth, sub- 
convex. Beneath, hlack ; epipleurae of thorax shining, impunctate, pros- 
ternum coarsely punctate, sometimes with a smooth space in the middle, 
margined between the front coxa?, mesosternum visible, declivous, meta- 
sternum moderately long, smooth, shining, hind margin almost straight and 
not emarginated by the hind coxa?, marginal line feebly punctulate in front,

more or less infuscate, sometimes entirely testaceous. Length 1.50-1.75 
mm.; .06— .075 inch. 

Enterprise and New Smyrna, many specimens, in May and 
June. This species has exactly the aspect of a small Crejpi- 
dodera and is distinguished by its less convex form, by the 
quadrate thorax, which is much narrower at the base than 
the elytra, and by the form of the metasternum. The sculp- 
ture of head and thorax is subject to variations as in the 
other species ; but the form and sculpture of the sterna ap- 
pear to offer more reliable characters. 

29. Microrhopala floridaim. n. sp. — Elongate, parallel at the 
sides, moderately shining, uniformly blackish-blue. Head sculptured as 
in M. cyanea, second joint of antennae as long as wide, third joint a little 
longer. Thorax at base but little wider than long, narrowed in front, 
transversely convex, at the sides almost straight, base lobed in the middle 
and strongly sinuate each side, anterior angles acute, prominent, posterior 
angles obtuse ; very coarsely punctured and in some specimens with a fine, 
impressed median line. Elytra with eight regular rows of very coarse 
punctures, alternate interstices evidently carinate. Prosternum with coarse 
punctures, metasternum punctate at the sides, abdomen sub opaque, indis- 
tinctly punctulate. Length 3.75-4.5 mm. ; .15-.18 inch. 

Differs from M. cyanea by its narrower and more elongate 
form, less transverse thorax, and by the costate elytra. One 
specimen is almost pure black above. 

Sumter county, many specimens, also found in Tampa 
and Enterprise. 

30. Stroiigylium anthrax, n. sp. — Sub-opaque, deep black, and 
only the last joint of antennae yellowish. Head formed as in 8. tenuicolle, 
anteriorly sparsely and finely, posteriorly more strongly and densely punctu- 
late ; antennae slender. Thorax at base a little wider than long, at the sides 
slightly rounded anteriorly, parallel posteriorly, base feebly sinuate each 
side, front angles rounded, hind angles rectangular, not densely punctulate, 
and not grooved, basal margin less thickened than in S. tenuicolle. Elytra

with eight rows of coarse punctures, the inner two striae sub-impressed, 
interstices hardly, convex, impunctate. Length 13.50 mm.; .54 inch. 

One specimen from Enterprise ; another from the same 

locality is in the cabinet of Dr. LeConte ; lives on dead oak 

twigs. Of the size of S. tenuicolle, but less convex and easily 

distinguished by the sculpture of the elytra. 

31. Hymenorus dorsalis Zimm., MS.— Elongate-oval, sub-im- 
pressed, above sub-opaque, with sparse, long, sub-erect pubescence, beneath 
shining, piceous-red, antennae and legs red, elytra black, broadly red at base. 
Head strongly and sparsely punctate, angulated each side in front of eyes, 
which are larger and more approximate than in any other species be- 
fore me, antennas stout, two-thirds as long as the body, outer joints 
more than twice as long as wide, last joint of maxillary palpi with the 
apical side decidedly longer than the external. Thorax at base almost 
twice as wide as long, semicircular, finely margined, base feebly lobed in 
the middle, hind angles rectangular, moderately strongly not densely 
punctured. Elytra punctate striate, striae hardly impressed with the punc- 
tures finer than those of the thorax and not closely placed, interstices 
flat, finely and sparsely punctulate ; the red color occupies not quite one- 
third of the length of the elytra. 

Tampa and Enterprise, two specimens, beaten from old 
palmetto leaves. Distinguished from the Other sub-opaque 
species by the larger eyes, by the not dense punctuation of 
the thorax, by the sculpture of the elytra and by its color. 

32. Isomira valida, n. sp. — Elongate-oval, convex, piceous, less 
shining, with moderately dense sericeous pubescence; antennae, palpi, tibiae 
and tarsi dark red. Head densely punctured, eyes very large, coarsely 
granulated, much less widely separated from each other than in /. ^-striata, 
antennae slender, more than half the length of the body, second joint not 
quite half as long as the third, the latter as long as each of the following 
joints, last joint of maxillary palpi less broadly triangular than in /. 4- 
striata, apical side shorter than the external, inner side straight. Thorax 
twice as wide as long, on the sides strongly rounded, and strongly narrowed 
from base to apex, base slightly sinuate each side, finely margined, hind 
angles rectangular ; densely punctate, in front of the scutellum with a short 
smooth, impressed median line, basal impressions feeble. Elytra at base 
twice as wide as the thorax, and three and a half times as long, densely, 
less finely punctulate, punctures forming transverse rugosities, obsoletely 
striate-punctate, the two inner striae impressed behind. Epipleurae of 
thorax, pro- and mesosternum densely rugosely punctulate, metasternum 
strongly punctured, posteriorly smooth, shining ; abdomen densely, finely 
punctulate. Length 6.75-7.50 mm.; .27-. 30 inch 

Enterprise, four specimens, found in May, under old leaves. 



1878. "'■*- [Schwarz. 

Larger and broader than 1. quadri striata, with the eyes 
much larger, the thorax wider, more arcuate on the sides, 
elytra denser and stronger punctate with the striae on the disc 
more evident, underside less shining, more densely punctate. 
The elytra are in fact regularly striate-punctate, but the 
striae are not impressed and the fine lines of punctures are 
confused by the equally strong punctuation of the inter- 
stices. 

33. Xylophilus quercicola, n. sp. — More elongate than any other 
species before me, having the appearance of a small AntMcus. Head, with 
the eyes, a little wider than the thorax, convex behind, piceous, finely, not 
densely pubescent, minutely and sparsely punctulate, eyes widely sepa- 
rated, not oblique, antennae red, longer than head and thorax, with moder- 
ately long, soft pubescence, intermediate joints longer than wide, outer 
joints as long as wide, penultimate joints subtransverse, terminal joint 
black, larger than the preceding, ovate, acuminate. Thorax as long as 
wide, at the sides rounded anteriorly, a little narrowed behind, base 
straight, hind angles obtuse, disc moderately convex with an obsolete im- 
pression each side in the middle, without basal impression ; sub-opaque, 
finely pubescent, minutely, sparsely punctulate ; color variable, testaceous

almost twice as wide as the thorax, elongate, parallel on the sides ; on the 
disc anteriorly depressed, sub-opaque, alutaceous, moderately strongly, not 
densely punctate, smooth at apex ; whitish pubescent, testaceous, an in- 
definite circum scutellar spot, a large spot each side behind the middle, the 
apex and sometimes the side margins black, the black color of the apex 
ascends along the suture. The pubescence is sparse on. the black and dense 
on the testaceous parts. Beneath rufous, pubescent, sub-opaque, punctate, 
abdomen often blackish, impunctate ; legs testaceous. Length 1.75 mm. ; 
.07 inch. 

Tampa, seven specimens, on oak shrubs, in April. I do 
not perceive any sexual characters. 

34. Xylophilus ptinoides, n. sp. — Piceous, sub-opaque, sparsely 
pubescent. Head, with the eyes, wider than the thorax, immersed in the 
thorax almost as far as the eyes, neck and hind margin of head, therefore, 
not visible ; front but little convex transversely ; finely and densely punc- 
tulate, eyes large, oblique ; antennae slender, two-thirds as long as the 
body, with long, stiff pubescence, pale yellow, third and fourth joint more 
than twice as long as wide, the outer joints still longer ; last joint as long, 
and a little wider than the preceding, obtusely rounded at tip, infuscate. 
Thorax as long as wide, quadrate, very convex transversely, not rounded 
on the sides, front margin straight, base rounded, opaque, densely and finely

indefinite impressions, with no distinct basal impression ; color piceons, 
base and apex reddish. Elytra oblong, at base twice as wide as the thorax, 
parallel at the sides, somewhat shiniug, coarser and less densely punctured 
than the thorax ; near the base with a reddish, angulated, whitish, pubes- 
cent fascia, near the apex with several other whitish pubescent spots, which 
form two interrupted fasciae. Beneath piceous ; sterna opaque, finely pubes- 
cent, densely punctulate ; abdomen glabrous, shining, at base coarsely, at 
tip finely punctulate. Front legs and all the tibiae pale, intermediate 
femora infuscate at base, hind femora piceous. Length 1.5 mm. ; .06 inch. 

Enterprise and New Smyrna, two specimens, in which I 
do not see sexual characters. This species has the appear- 
ance of a small Ptinus, and is distinguished at once from all 
species, except the X. ventricosus Lee, by the form of the head. 
The latter species has the head still more immersed in the 
thorax, the eyes touching the front margin of the thorax, 
but is otherwise quite distinct from X. piinoides. 

35. Glipa hieroglypliica, n. sp. — Elongate, cuneiform, black, 
head anteriorly densely covered with yellowish cinereous pubescence, 
posteriorly more sparsely pubescent, hind margin fringed with cinereous 
pubescence ; antennae from the fourth joint broadly serrate ; maxillary 
palpi testaceous, upper edge black, last joint very broadly securiform, flat, 
apical edge not hollowed out. Thorax transverse, at apex produced in the 
middle, basal lobe rounded ; densely punctulate, cinereo-pubescent, with 
the usual black spots. Scutellum rounded triangular, densely whitish 
pubescent. Elytra opaque, densely punctured, grayish pubescent ; each 
with a narrowed angulated line, which begins at the scutellum and ends 
at the side margin a little before the middle, resembling rudely the figure 
5 on the left, and on the right elytron the same figure reversed, and with a 
narrow oblique fascia at the apical third, cinero-pubescent. Beneath 
densely cinereo-pubescent ; anterior femora pale testaceous, black at tip, 
anal style long, carinate above, at the tip emarginate, and densely cinereo- 
pubescent, fifth ventral segment longitudinally excavated. Length 10.5- 
11.25 mm. ; .42-45 inch. 

Enterprise, four specimens in May. In one specimen the 
penultimate joint of the maxillary palpi is fringed intern- 
ally with dense whitish pubescence ; this is probably the d\ 
I have not been able to compare this species with G. hilaris, 
which, according to the description given by Dr. LeConte 
(Proc. Ac. Nat. Sc, Phil., 1862, p. 46). has the last joint of 
the maxillary paVpi hollowed out, and which has different 
markings on the elytra.*

Additional Descriptions of New Species. 
By John L. LeConte, M. D. 

1. Dyscliirius falciger, n. sp. — Rather slender, black, very shining, 
with a slight brown-metallic tinge; palpi, antennae and legs ferruginous. 
Head smooth, convex, with the frontal and tranverse impressions deep ; 
front truncate, with small, acute lateral angles. Eyes convex, prom- 
inent, as usual. Prothorax about as wide as long, rounded on the sides, 
narrowed in front, lateral impressed line not continued to the base. Elytra 
w r ith striae coarsely punctured at base, gradually becoming finer, obliter- 
ated at about three-fourths of the length ; tip with faint traces of striae, and 
a rather large, oblique impression, representing the end of the 7th stria. 
Front tibiae with a small, acute tooth above the apical prolongation, which 
is straight and slender ; apical spur very long and strongly curved. Length 
3 mm.; .12 inch. 

Tampa and Lake Harney ; received also from Dr. Emil 
Brendel. This species is not as slender as D. terrninatus, but 
is proportioned like D. analis, from -which the characters 
given above easily distinguish it. D. curvispinus Putz., is 
described as having the apical spur of the front tibiae curved, 
but it is otherwise quite distinct by the ferruginous color, 
and by the strise of the elytra not obliterated towards the 
tip. The prsescutellar puncture in this species is large, and 
the dorsal punctures usually seen on the 3d interspace are 
not apparent. 

2. Onota trivittata, n. sp. — Elongate, depressed ; bright rufo-tes- 
taceous, shining. Head narrowed and rounded behind the eyes, fiat, with- 
out impressions ; edges larger and more prominent than usual. Prothorax 
not as wide as the head with the eyes, longer than wide, narrowed behind, 
sides rounded in front, then sinuate to the basal angles which are not 
rounded, and slightly divergent ; side margin reflexed, not very narrow, 
dorsal line fine, basal impressions small. Elytra wider than the prothorax, 
oblong, truncate at base, somewhat obliquely, broadly truncate at tip, flat, 
side margin reflexed, striae composed of very fine punctures ; ornamented 
with a common sutural black stripe, and a sub-marginal one, which ex- 
tends along the apical truncature to meet the sutural one ; the latter ex- 
tends to the 2d stria, and behind the middle is slightly dilated for one- 
fourth the length to reach the 4th stria. Beneath uniform rufo -testaceous. 
Length 5 mm.; .20 inch. 

Florida, collected by Mr. A. Bolter, of Chicago, to whom 



LeConte.J 614: [ Feb# 1> 

I am indebted for two specimens. This beautiful species is 
easily recognized by the peculiar coloration. I have referred 
it to Onota Chaud.. because the 4th joint of the tarsi is broad, 
and deeply bilobed, and the claws are pectinate. The teeth 
of the claws are only four in number, and are much larger 
than in the other species. The tarsi are glabrous on the 
upper surface. The last joint of the maxillary palpi is cylin- 
drical, slightly oval, and more than twice as long as the pe- 
nultimate joint ; the last joint of the labial palpi is oval, 
pointed and somewhat flattened. Mentum not toothed. It 
is by this last character that it mainly differs from Callida, 
with which it agrees in having two bristles near the tip of 
the ligula. 

3. Platynus floridanus, n. sp. — Dark green, shining, slightly 
bronzed, antennae, legs and under surface piceous-black. Prothorax 
scarcely longer than wide, sides broadly rounded, and finely margined ; 
apex emarginate, front angles slightly rounded ; base broadly sub trun- 
cate, oblique towards the side angles, which are obtuse and almost 
rounded ; basal impressions rather long, not punctured ; dorsal line ex- 
tending to the posterior transverse impression, which is faint. Elytra one- 
third wider than the prothorax, emarginate at base, obsoletely sinuate at 
tip ; stria? fine, but well impressed, not punctured ; interspaces fiat, 3d with 
usually small dorsal punctures, the 1st and 2d adjacent to the 3d stria, 3d 
and 5th upon the interspace, 4th and Gth adjacent to the 2d stria. Hind 
tarsi with the 1st, 2d, and 3d joints broadly grooved on the outer side. 
Length 9.6 mm. ; .35 inch. 

Capron and Lake Harney, abundant. This species is 
closely related to P. californicus, and differs only by the 
hind angles of the prothorax being much less distinctly de- 
fined; in fact, almost rounded. The size is usually larger, 
so that the smallest individuals of P. floridanus are equal to 
the largest of californieus, but this is a character of small im- 
portance. Closely allied to these two is the following : 

4. Platynus texanus, n. sp. — Less shining, with a green-metallic 
reflection. Antennae black ; under part of 1st joint, palpi and legs testa- 
ceous ; knees, tarsi and tips of tibiae blackish-piceous. Prothorax, as in 
P. floridanus, except that it is a little wider than long. Elytra simi- 
larly striate and punctured, but with the striae a little deeper ; epipl curse 
testaceous, under surface black. Groove of the outer side of the hind tarsi 
on the joints 1-3 deep Length 9-10 mm. ; .35-40 inch.

Abundant in Texas. For a good set I am indebted to Mr. 
G. W. Belfrage, of Clifton, Bosque county. 

Several new species of Loxandrus were collected in Florida 
by Messrs. Schwarz and Hubbard, and full sets of previously 
known, but rare species were obtained. Under these cir- 
cumstances, though I cannot, without reference to types con- 
tained in Baron Chaudoir's cabinet, prepare an exhaustive 
synopsis of the genus, the following table of the differences 
between the species I have examined may be found useful: 
Table of Species of Loxandrus. 

A. Side margin of protliorax explanate and reflexed towards the hind 
angles, which are entirely rounded into the base and sides ; antennae and 
palpi rnfo-piceons, legs dark : (species large and middle sized). 

B. Side margin of protliorax not explanate towards the hind angles, 
which are not rectangular : (species large and small). 

C. Side margin of prothorax not explanate towards the hind angles, 
which are rectangular : (species small). 

A. 
Large species (length 13.3-10 mm. ; .52-. 40 inch) 2. 

Smaller species, with hind angles of prothorax less broadly rounded 
(length 10-7.8 mm.; .40-.31 inch) 3. 

2. Side margin of prothorax broader and more distinctly reflexed towards 

the base ; elytra with more finely punctulate striae, iridescent reflec- 
tions less brilliant 1. reflexus, n. sp. 

Side margin of protliorax less definitely limited towards the base ; 
elytra with less finely punctured striae ; iridescent reflections very 
bright 2. saphyrinus. 

3. Protliorax regularly narrowed from base to tip, sides feebly explanate 

towards the base 3. calathinus, n. sp. 

Protliorax but slightly narrowed in front ; sides more distinctly ex- 
planate towards the base 4. floridanus, n. sp. 

B. 

Larger species (length 13-9.3 mm.; .50-. 37 inch) 2. 

Small species (length 7.7-5.8 mm. ; .32-225 inch) 4. 

2. Legs dark 3. 

Legs ferruginous, prothorax wider than long, hind angles obtuse, blunt 

or rounded at tip 5. rectus. 

3. Prothorax wider than long, hind angles slightly obtuse, not at all 

rounded 6. brevicollis. 

Prothorax very slightly wider than long, hind ; ngles rounded at the 

extreme tip 7. minor. 

Proth. not wider than long, hind angles not rounded 8. erraticus. 



LeConte.J *37b [Feb. I, 

4. Legs dark, hind angles of prothorax not rounded ; elytra with a round 

sutural red spot behind the middle 9. celer. 

Legs dark, hind angles of prothorax rounded at tip ; varies with the 
legs brown-ferruginous, seems to pass insensibly to L. velox. .10. agilis. 

Legs yellow, hind angles of prothorax rounded at tip 11. velox. 

a. Prothorax rounded on the sides ; not conspiculously wider than long ; 
velox. 

/?. Prothorax rounded on the sides, conspicuously wider than long ; 
pusillus. 

y. Prothorax nearly square, less rounded on the sides ; tamiatus, pici- 
ventris. 

C. 

Legs dark, elytral stride feebly punctured., 12. rectangulus, n. sp. 

Legs yellow, etytral stria? coarsely punctured 13. crenatus. 

5. Lo valid in* reflex us. n. sp. — Black, very shining, with irides- 
cent reflection. Prothorax wider than long, feebly emarginate at apex, 
equally feebly rounded at base, sides and hind angles rounded ; side margin 
reflexed, narrow in front, becoming much wider behind, so as to extend 
at the base to the basal impressions, which are linear and deep ; dorsal line 
very fine, transverse impressions obsolete. Elytra not wider than tbe pro- 
thorax, striae finely punctured in front, deeper and not punctured behind, 
antennae, palpi and tarsi piceous-brown. Length 10-13 mm. ; .40-. 50 inch. 

Tampa, not rare. This fine species has much resemblance 
to L. saphyrinus, which occurs in Louisiana ; but on com- 
parison, the iridescent reflection is less vivid, the prothorax 
is less rounded on the sides, the broad part of the reflexed 
side margin towards the base is much better defined, and 
finally the elytral stride are much more finely punctured from 
the base to the middle. 

6. Loxaiidrus calathiiius, n. sp. — Elongate-oval, black, very 
shining, slightly iridescent ; tarsi and antennae piceous, the latter with 
joints l-3d, and palpi dark ferruginous. Prothorax wider than long, much 
narrower in front than behind, broadly rounded on the sides, which are 
broadly but not strongly explanate towards the base ; hind angles dis- 
tinct^ rounded at tip, basal impressions linear, as usual deep. Elytra with 
the striae finely but distinctly punctured. Length 8.8-10 mm. ; .35-40 inch. 

Tampa, Florida ; not common. 

7. L.oxandrus floridanus., n. sp. — Black, very shining, irides- 
cent ; antennae and legs piceous or blackish, base of the former, palpi and 
tarsi ferruginous. Prothorax wider than long, scarcely narrower in front 
than at base, sides rounded, broadly but slightly explanate towards the 
base ; hind angles obtuse and more rounded at the tip than in L. calathinus, 



**• • [LeConie. 

basal impressions linear, not very deep. Elytra with the striae feebly ana 
finely punctulate. Length 7.4-8.5 mm.; .29-33 inch. 

Capron and Enterprise ; abundant. Varies in color accord- 
ing to maturity, so that the tibire and sides of the thigns 
also become yellow-brown. In some specimens the sides of 
the prothorax are less distinctly explanate, and such, except 
by their larger size, are difficult to distinguish from L. agilis. 

8. Loxaudrus rectangiilus, n. sp. — Black, very shining; slightly 
iridescent; antennas and legs piceous, or blackish. Prothorax wider than 
long, slightly narrower at tip than at base, sides rounded, not sinuate 
behind, bind angles rectangular, not at all rounded ; side margin more 
broadly reflexed towards the base, sides not explanate ; base with a few 
scattered punctures, impressions linear, deep. Elytra distinctly wider than 
the prothorax, striae not punctured. Length 6.5 mm.; .25 inch. 

Enterprise, May; rare. This species and crenatus, by hav- 

the elytra wider than the prothorax resemble in form certain 

Platyni and Bembidia. There are but two specimens before 

me ; in the r the elytral striae are much deeper than in the d\ 

9. Selenophorus excisus, n. sp.— Oblong, aeneous, sub-depressed; 
legs and antennas piceous, first joint of antennas ferruginous. Prothorax 
nearly twice as wide as long, rounded on the sides, which are finely mar- 
gined, a little narrower at base than at tip ; hind angles rounded, basal im- 
pressions shallow, not punctured. Elytra deeply sinuate at tip ; humeri 
rounded, striae fine, interspaces flat ; punctures of the three series rather 
large and conspicuous. Hind tarsi long and slender, Length 5.5 mm.; 
.22 inch, 

Southern Florida, Dr. Palmer, 3 specimens. Of the same 
size, form and characters as S. fatuus, from which it differs 
by the punctures of the three elytral series being much 
larger, and by the hind angles of the prothorax more obtuse 
and more rounded. The outer interspaces of the elytra are 
not all punctulate. 

10. Hydroporus semiiiuluiii, n. sp. — Broadly ovate, obliquely 
attenuate behind, rounded in front, not very convex ; rufo-testaceous, 
shining. Prothorax scarcely perceptibly punctulate, with a fine short 
basal stria each side, which does not extend upon the elytra ; the latter 
very finely, though distinctly punctulate. Beneath sparsely but strongly 
punctured. Length 1.3 mm. ; .05 inch. 

Enterprise, one specimen. Of the same size as H. granum, 
but very different by the body being strongly narrowed

behind the middle, and pointed at the posterior end. Differs 
also from all previously known small species of the United 
States, by the thorax having a very short basal stria not con- 
tinued on the elytra. 

11. Dineutes angustus^ n. sp. — Narrower, smaller and more con- 
vex than D. discolor, elongate-oval, slightly narrowed in front, bluish- 
black, with slight metallic gloss. Prothorax very little wider than the 
head, sides straight, slightly oblique, transversely very convex. Elytra 
sparsely, nnel}^ punctured, stria? obliterated ; sides feebly and narrowly ex- 
planate, scarcely undulated near the apex, which is (9) obtusely pro- 
longed. Under surface and legs rufo-testaceous. Length 9.5 mm. ; .375 
inch ; breadth 4.5 mm.; .175 inch. 

Three females, collected by Dr. Palmer. The marginal 
line of the front margin of the prothorax is less interrupted 
in these specimens than in D. discolor, but I do not think 
this a character of any value. 

Table, of Specie* of Ociithebius. 

The number of species of Ochthebius in our fauna has increased to such 
an extent, that the recognition of the three new species collected by Mr. 
Schwarz would be facilitated by the description of those from other 
parts of the country. The following table contains those which I have been 
able to examine :

slightly wider towards the base 4. 

3. Discoidal impressions united, forming a groove each side of the dorsal 

channel, sides of disc of prothorax curved 1. puncticollis. 

Discoidal impressions separate, sides of disc of prothorax curved

two deep, oblong impressions each side, and another half way to the lat- 
eral margin. Elytra but slightly wider than the prothorax, strise deep, 
closely punctured, fainter and nearly obliterated at tip. Legs and under 
surface dull testaceous. Length 2 mm.; .075 inch. 

California, Sau Mateo, Gilroy and San Diego ; Mr. G. R. 
Crotch ; Dr. Horn has received a smaller specimen from 
Canada. Resembles 0. puncticollis, but is smaller and less ro-

not deep, discoidal impressions. 

15. OclitlieMus simplex, n. sp.— Oval, more convex, bronzed, less 
shining. Head sparsely, strongly punctured, with two occipital foveas, 
and deep frontal suture. Prothorax wider than long, slightly narrowed 
behind, pellucid margin very narrow, visible behind the middle ; disc

to a specimen which differs only by the punctures of the 
elytral Btrise being less distant. Allied to this, but appa- 
rently distinct is : 

17. OclitlieMus laevipennis, n. sp. — Dark piceous-bronze, very- 
convex, shining, of the same form as 0. nitidus. Head with two large 
deep fovea?, and a deep transverse suture. Prothorax with deep dorsal 
line, two small foveas each side in front of the middle, a deep impression 
near the apical margin, towards the anterior angle ; sides deeply lobed as 
in 0. nitidus, pellucid margin broad, with an undulated outline. Elytra 
with deep, humeral fossae ; striae obsolete, traced only by a few fine, dis- 
tant punctures near the base. Under surface piceous, legs testaceous. 
Length 1.3 mm. ; .03 inch. 

Tejon, California ; one specimen, Dr. Horn. It is possible 
that this is an extreme variety of 0. nitidus, but until the 
intermediate forms are collected, it should properly be known 
under a different name. 

18. OchtlieMus foveicollis, n. sp. — Closely resembles 0. nitidus, 
hut the elytra are longer, more obliquely narrowed behind, and the striae 
are composed of rather large, close-set punctures, not less distinct towards 
the tip. From 0. tuberculatus, it differs by broader prothorax, with larger 
lateral pellucid spot, and broader anterior lobes of the disc. Length 1.2 
mm. ; .018 inch. 

Enterprise and Lake Harney, Florida, May ; not rare. 

19. OclitlieMus benefossus, n. sp. — Oval, moderately convex, 
bronzed, shining. Head sparsely punctured, with two very large foveae 
connected behind ; transverse suture deep. Prothorax wider than long 
(pellucid margin ?) disc with the sides straight from the anterior angles to 
the middle, then strongly narrowed to the base (making a concave outline 
which must be filled with membrane in well preserved specimens) - r 
sparsely punctured, dorsal channel very deep, discoidal impressions deep, 
the posterior ones connected in a horse shoe form. Elytra with striae com- 
posed of punctures distant from each other about their own diameters, 
basal fossae small. Beneath piceous, legs testaceous. Length 1*5 mm. ; .06 
inch. 

New Jersey, Dr. Horn. Nearly of the same form as 0. 
nitidus, but different by the disc of the prothorax not being 
lobed at the side behind the front angles, as well as by the 
style of sculpture, which is more simple, and tends towards 
0. Holmbergi and allies. 

20. OchtheMus sculptus, n. sp. — Elongate-oval, greenish-piceous, 
slightly bronzed, shining. Head sparsely punctured with deep frontal su-

ture, and three occipital fovea? of equal size. Protliorax broader than long, 
distinctly narrowed behind; pellucid margin rounded, dilated inwards 
towards the base ; disc feebly lobed at the sides ; feebty punctulate at the 
middle, more distinctly towards the sides ; with two vague transverse im- 
pressions, one before, the other behind the middle ; dorsal line interrupted, 
sometimes obsolete, discoidal lines sinuate, well marked ; lateral im- 
pression large. Elytra with rows of tine, close-set punctures, not effaced 
towards the tip. Legs dark testaceous. Length 1.5 mm.; .06 inch. 

Gilroy, California, Mr. Crotch; Arizona, Dr. Horn. A 
nearly similar specimen from Canada is also in his collec- 
tion ; it is rather stouter in form, and the prothorax is more 
narrowed behind, but I am unwilling without a larger series 
of specimens to consider it distinct. 

RHIXOSCEPSIS n. g. (Pselafhid^.) 

Head sub-pentagonal, a little longer than wide, sides parallel behind the 
eyes, base truncate, hind angles rectangular, rounded at tip. Antenna? 
inserted under a narrow fronjal protuberance (which projects over the 
mouth, somewhat like the prothoracic horn of Notoxus), 1st and 2d joints 
thick, the former nearly twice as long; 3d— 8th small, rounded; 9th rounded, 
a little larger ; 10th slightly wider ; 11th ovate, acute at tip, longer than the 
three preceding united. Maxillary palpi as long as the head, slender, last 
joint ovate acute, similar in form to the last joint of the antennae. Prothorax 
pentagonal, not convex, with a deep sub-interrupted dorsal channel, and a 
transverse impression behind the middle. Elytra not convex, with a deep 
sutural stria, a fine dorsal one near the sutural, a sub-apical fovea near the 
sides, and a marginal stria nearly as deep as the sutural. Dorsal surface of 
abdomen broadly margined, segments 1— 3d equal in length. Tarsi with a 
single claw. 

$. Penultimate ventral segment strongly and broadly emarginate, last 
segment longitudinally impressed ; front tibiae much thicker at the middle. 
gradually attenuated at base and tip. 

9- Last ventral segment large, semi-circularly impressed In front, with 
a few long hairs intermixed. 

21. R. bistriatus, n. sp. — Brown, sub-depressed, not shining, finely 
pubescent, Head with two occipital foveas and an elongate, but not deep 
frontal impression ; eyes very small, rounded ; prothorax scarcely wider 
than long, dorsal channel deepest at the intersection with the transverse 
impression. Elytra with sutural, and marginal striae very deep, a fine 
dorsal stria near the sutural, and sub-apical fovea near the marginal stria ; 
surface finely punctulate ; wider than the prothorax, graduall}- broader 
from the base almost to the apical truncature. Abdomen a little longer than 
the elytra, finely punctulate. Length 1 mm.; .041 inch.

Enterprise and Tampa. This genus exhibits an odd 
mixture of characters. It resembles in form and sculpture 
the new species of lihexius described below, and has also the 
appearance of Trichonyx, but it differs from those genera by 
the insertion of the antennas, which are approximate, and 
situate under the frontal protuberance, which is longer than 
in any other genus yet known as belonging to our fauna. It 
resembles, so far as I can judge by the figure and description, 
the Grecian genus Panaphantus Kiesenw. Berl. Ent. Zeitschr.

than R. insculpius. Head with two fovea? and a frontal impression ; occiput 
very finely carinate ; eyes small. Prothorax finely channeled, with three 
large impressions near the base. Elytra with basal margin elevated, i ost- 
basal fovea? deep, each with four faint stria?, of which the sub-sutural one is 
longer and more distinct, the others extending only to about the middle.

slightly pubescent. Head with a large deep angulated impression, front 
concave, occiput convex, smooth. Prothorax longer than wide, convex, 
subcorclate, rounded on the sides in front, then narrower and broadly

Cambridge, Massachusetts ; Mas. of Comp. Zoology ; one 
specimen, collected in December, by Mr. II. G. Hubbard. 
The palpi are rather short, with the last joint ovate-pointed 
as in the preceding, but it differs from that, as from all the 
others in our fauna, by the foveas of the head being much 
nearer the eyes. The eyes are more lateral and prominent, 
and have not a shallow groove and elevated margin above 
them. This margin, though not strongly marked, is seen 
in the other species, and separates the upper surface of the 
cranium from the sides.

Mr. Fauvel (Faun. Gallo-Rhen. iii, 542) states that A.pra- 
tensis Lee. is the same with A. glabricollis of Europe. I have 
not compared specimens, but think that the finer punctua- 
tion of pratensis entitles it to distinct recognition, and that 
Mr. FauveFs remark will apply better to some of the black- 
legged varieties of what we consider A. pronus.

the margin, in front of the middle ; three small marginal ones behind the 
middle, and a few on the basal margin. Elytra smooth, with obsolete su-

length. ^ 3d ventral with a round flat slightly elevated tubercle. 

Bosque Co., Texas, Mr. GL W. Belfrage ; Arizona, Dr. 
Horn. This species is an excellent example of what is not 
unfrequently seen in other families ; the union of characters 
which define two or more separate groups of species, with 
some peculiar character. In this instance the sexual charac- 
ters of the dV of the two groups of § A are united, but the 
form of head is quite different from that seen in either of 
them. 

43. [17.] C. lugubre, n. sp. — Slender cylindrical, shining black ; legs, 
palpi and antenna? yellow, the latter darker at the base. Head as long as 
the prothorax and very little wider, sparsely strongly punctured, punctures

smaller and indistinct upon the front. Prothorax with smooth dorsal stripe 
broad, sides strongly sparsely punctured. Elytra with rather large punc- 
tures arranged somewhat in rows. Abdomen sparsely finely punctured, 
tip and posterior border of segments brown ; ventral segments brown. 
Length 6 mm. : .24 inch. 

tf and 9 ~d ventral segment with a small tubercle bearing two small 
stout black setae resembling spines ; ^ ? 3d ventral segment marked 
with a small fovea. 

The last joint of the maxillary palpi is about one-third the length of the 
3d joint. The elytra are a little shorter than the prothorax. 

Tampa and Enterprise ; three q . On examining seven 
specimens, I find no difference in the ventral segments, ex- 
cept that in all of them the 2d (apparent) segment has a 
small transverse impression and fold, bearing spines ; while 
in two of them the 3d segment has also a small round fovea 
at the middle, a little nearer the front than the hind margin. 
There is no difference in the size of the head. 

44. [18.] CryptoMum oMiquum, n. sp. — Slender, cylindrical, 
shining, black ; antennae, palpi, and legs yellow. Head as long as the pro- 
thorax, distinctly wider, sides oblique behind the eyes, and broadly round- 
ed ; eyes rather large, convex ; sparsely punctured, front smooth, with only 
a few scattered punctures, the smooth space prolonged behind to between 
the eyes. Prothorax with smooth, dorsal stripe wide, not well defined ; sides 
sparsely, strongly punctured, punctures arranged almost in rows. Elytra 
coarsely punctured, here and there almost in rows. Abdomen sparsely 
punctured, nearly smooth towards the tip, which is brown. Length 6 mm.; 
.24 inch. 

$ 3d ventral segment with a long, triangular setose process, rounded at 
tip ; 2d and 3d segments not distinctly impressed. 

9 2d and 3d ventral segments, each with a very small bisetose fovea. 

Tampa; April, one pair. Quite different from C. lugubre 
by the form of the head. 

45. [19.] CryptoMum pare u m, n. sp. — Cylindrical, shining, 
black, antennae, palpi, and legs yellow. Head as long as the prothorax,

rather large, convex ; punctured as in C. obliquum. Prothorax with 
smooth dorsal stripe, sides sparsely coarsely punctured in rows. Elytra as 
long as the prothorax, coarsely punctured, here and there in rows. Abdo- 
men sparsely less finely punctured, tip brown. Length 6 mm. ; .24 inch. 

9 2d and 3d ventral segments not impressed 

Cedar Keys ; June, one 9. Differs from C. obliquum chiefly 
by the less slender form, coarser punctures of the prothorax, 
and absence of ventral impressions.

46. [21.] CryptoMum lepidum, n. sp. — Slender, less convex, 
ferruginous, shining, pubescence fine. Head oval, nearly as long as the 
prothorax, and wider than it, sides much rounded behind the e} r es, which 
are rather large and convex ; sparsely, equably punctured, front not less so 
than the rest of the surface ; there are two long, but not deep frontal im- 
pressions. Prothorax with smooth dorsal stripe narrower than usual, lim- 
ited each side by a row of points, which becomes a slightly impressed stria 
towards the base ; sides rather sparsely punctured, almost in rows. Elytra 
distinctly longer than the prothorax densely, rather finely punctured. Ab- 
domen sparsely punctured. Legs paler. Length 3.8 mm. ; .15 inch. 

Bosque County, Texas, Mr. G. W. Belfrage, two 9. The 

ventral segments are not impressed. A very small and pretty 

species, less convex than the others in our fauna. 

47. Paederus otoliteratus, n. sp. — Elongate, slender, reddish-yel- 
low, shining ; head and last two abdominal segments black ; above yellow ; 
elytra blue-black ; antennas brownish at the middle. Head sparsely punc- 
tured, slightly wider than the prothorax ; the latter elongate-oval, feebly 
sparsely punctured, elytra not longer than the prothorax. sparsely but not 
coarsely punctured at the base, nearly smooth behind the middle. Dorsal 
segments very sparsely and finely punctured. Length 5 mm.; .20 inch. 

C? Sixth ventral cleft nearly to the base ; cleft wide, rounded at the an- 
terior extremity. 

Southern part of Florida, Dr. Palmer ; Mr. E. P. Austin 
gave me a similar specimen as found at Cambridge, Massa- 
chusetts. This species is easily distinguished by the finer 
punctures of the elytra becoming gradually obliterated be- 
hind. 

Larger series of specimens have indicated to me the neces- 
sity of some modifications in the table of species of this 
genus published by Mr. Austin, (Proc. Bost. Soc. Nat. Hist. 
xix, 47); and I would propose to substitute for it the fol- 
lowing synopsis :

Length 3.4 mm. ; .13 inch. 

Tampa, Enterprise and Capron ; not rare. Agrees in color 
with P. pallipes, but differs by the smaller size, and by the 
elytra being as long as, or very little longer than the pro- 
thorax. Abdominal segments alike in both sexes. 

The species of Palaminus agree in form and sculpture, and 
the antennae, palpi and legs in all are pale yellow. The other 
characters enable those in our fauna to be distinguished as 
follows:

gularly emarginate 4. testaceus. 

* Note.— I have omitted JP. ustus, which belongs to a different group of species 
having the color nearly uniform testaceous. P. nevadensis Austin, does not 
differ from compotens Lee. By a confusion of specimens the remarks of Mr. 
Austin concerning P.grandis Austin, are incorrect; the species is easily known 
by the large size, equal to P.femoralis, and the strongly margined, concave 
epistome.

coarsely punctured. 

54. Palaminus larvalis Lee, New Sp. Coleopt. (Smiths. 8vo.)49. 
In this species the head and protliorax are sparsely and coarsely punctured ; 
the protliorax is nearly as wide as long, ovate, strongly narrowed behind, 
and oblique on the sides, as in P. cribratus ; the elytra are not longer than 
the protliorax and a little narrower, convex, very coarsely and sparsely 
punctured. Length 3.1mm.; .12 inch. 

New York, Tennessee ; Palatka and Tampa, Florida. 
~No sexual differences are apparent in four specimens ex- 
amined. This species closely resembles P.flavipennis, but 
can be distinguished from immature specimens of that spe- 
cies by the elytra being a little narrower than the prothorax, 
and by the smooth dorsal line of the latter not being ele- 
vated towards the base. 

55. Bracliypeplus glatoer, n. sp. — Elongate, very depressed, red- 
brown, abdomen piceous. Head and prothorax finely rather densely punc- 
tured, the latter more than one-half wider than long, scarcely narrower in 
front, sides nearly straight, slightly rounded near the anterior margin, 
which is truncate ; sides finely margined, narrowly explanate towards the 
hind angles, which are rectangular. Scutellum finely punctured, transverse, 
5-sided. Elytra about twice as long as the protliorax, strias punctured, well 
impressed, interspaces flat, each with a row of punctures. Dorsal segments 
sparsely punctulate, fimbria? widest behind, narrowest at the middle, with 
the inner outline concave ; fimbria of last segment widest at base, gradually 
narrowed behind. Length 3.2 mm.; 13 inch. 

Enterprise ; May. Differs from all the tropical American 
species described by Murray (Trans. Linn. Soc, London, 
xxiv, 296), bj' the absence of pubescence. It therefore be- 
longs to his sub-genus Leiopeplus, thus far known only from 
Western Africa. 



L878. ""•' [LeConte. 

SUIICRIPS, n. g. (Monotomid^e). 

Body elongate, sub-cylindrical, resembling in miniature a narrow species 
of Ips. Head as wide as the prothorax, not narrowed behind the ayes, 
which arc small, rounded and convex; narrowed in front of the eyes, epi- 
stoma wider than long, with sides parallel, separated from the head by a 
very deep frontal suture. Labrum transverse, broadly rounded ; mandi- 
bles strong, obtusely toothed. Palpi short, the labial ones broad. Men- 
turn with parallel sides, longer than wide. Antennae inserted in the cly- 
peal suture, 11-jointed, joints 1 and 2 thick, 3-8 small, 9-11 forming a 
loose elongate club. 

Prothorax nearly square, front angles rounded, side margin very fine ; 
presternum very narrow between the coxae, which are very small, and far 
back, at the hind margin of the prothorax ; coxal cavities small, oval. 
Middle coxae separated by the narrow mesosternum. Hind coxie widely 
separated. Ventral segments 5 ; 1st and 5th each as long as the three 
others united. Elytra parallel, scarcely wider than the prothorax, broadly 
truncate at tip, exposing a long pygidium. Legs rather short, tibiae gradu- 
ally thickened to the tip, Avhere there are a few small spines ; tarsi with 
the joints dilated, very short, last joint more than twice as long as the 
others united ; claws rather large, simple. 

56. S. palmicola, n. sp. — Elongate, reddish-testaceous, impercepti- 
bly punctulate above and beneath, and finely pubescent ; elytra with a 
transverse piceous cloud near the tip, and frequently another near the base. 
Length 1 mm.; .04 inch ; varies a little larger or smaller. 

<$ 5th ventral segment broadly impressed. 

Tampa, Haulover and Enterprise ; abundant on Chq^ncerops 
palmetto. I have also a specimen from Georgia ; a MS. draw- 
ing by my father bears the name Nitidula minutissima Dej. 
Cat. 

The quadrangular epistoma and deep frontal suture will 
enable this small insect to be easily recognized. The maxil- 
lae are unusually large and flat at the base, filling up the 
buccal cavity each side of the mentum. 

57. Scymnus Ibalteatus. — Elongate oval, brownish rufous, shining, 
punctulate and very finely, sparsely pubescent ; elytra tinged with piceous, 
ornamented with a broad oblique yellow band in front of the middle.

rounded. 

58. Scymiiusqiiadritaeniatus.— Elongate-oval, dull brown, punc- 
tulate and clothed with fine short gray pubescence. Elytra black, each 
with two large yellow spots, one before, the other behind the middle ; 
apical margin yellow. Prothorax rufous towards the sides, which are 
rounded and narrowed in front of the middle. Abdomen dark rufous, 
antennas and legs paler. Beneath finely and densely punctured, post-coxal 
arcs extending to the 1st ventral suture, effaced on the outer side. Length 
1.2-1.6 mm.; .05-. 06 inch. 

Varies with the yellow spots enlarged so as to become confluent. 

Enterprise and Capron ; rare. The variety is from Opelousas, 
La., and was kindly given me by Mr. Salle. The anterior 
spot is oblique on the inner outline, and the posterior one is 
transverse, and slightly sinuate behind. 

59. <Eneis pallida, n. sp. — Broadly ovate, convex, impunctured, 
testaceous, shining, glabrous; prothorax finely margined at base; front 
tibia? slender. Length 0.8 mm.; .035 inch.

of a pale color. 

6C. Pentilia misella . n. sp. — Rounded-oval, convex, shining, 
black, g^brous. Prothorax finely margined at base, sides not explanate 
nor punctured. Elytra a little wider than the prothorax, distinctly punc- 
tured, suture finely margined. Length 1 mm.; .04 inch. 

Tampa and Capron. A widely diffused species, found 
from Lake Superior to Florida, and from New York to 
Illinois. Sometimes abundant on the flowers of Thai vctrum. 
The two following species do not belong to this zoological 
province.

front, marginal line deep with a badly impressed frontal chevron. Prothorax 
punctured at the sides and front, smooth at the middle ; base with a 
narrow band of aciculate punctures. Elytra with a large, posterior sub- 
quadrate punctured space, extending from -the sutural stria to the 3d 
dorsal, and from the end of the 1st dorsal to the apical margin ; 1st and 
2d dorsal a little longer than the 3d and 4th ; the last named connected 
with the sutural, which is entire. Front tibiae with 3 large and 3 small 
teeth ; hind tibiae with spines arranged in two rows ; mesosternum smooth 
with the marginal line curved in front. Prosternum not compressed, striae 
approximate, abbreviate in front, divergent behind. Length 3.2 mm., .125 
inch. 

Southern Florida ; Dr. Palmer, two specimens. This and 
the next two species belong to my group VIII,* but it differs 
from those mentioned by Dr. Horn in having the punctured 
space of elytra limited in front by a transverse outline. The 
humeral stria, as usual, is long and fine, the external sub- 
humeral wanting, the internal short, disconnected. 
. This species has been previously known only from Mexico, 
and is perhaps only a variety of the next.

Southern Florida; one specimen, Dr. Palmer. This species 
only differs from the preceding by the punctures of the elytra

the sides and a large basal mirror smooth, punctures extending to the base 
between the 1st and 2d dorsal striae ; 1st dorsal longer than the others, ex- 
tending farther behind than the inner marginal, which is connected with

entire. Front tibiae with 3 large and 3 small teeth. Hind tibia? with two 
rows of spines. Mesosternum smooth, with the marginal line curved in 
front. Presternum with stria approximate, abbreviated in front, divergent 
behind. Length 3.8 mm. ; .15 inch. 

Cedar Keys ; on the beach, rare. Also allied to the two 
preceding, and intermediate between them in the puncturing 
of the elytra. It differs chiefly by the first dorsal stria being 
prolonged behind, to within a short distance of the tip, as in 
S. fraternus, &c, though in a less degree. 

66. Epierus brunnipeiiiiis Mars. Mon. Hister. (Ann. Ent, Soc. 
Fr. 1854), 697, fig. 18. 

Specimens found at Enterprise and Haulover, agree per- 
fectly with the description of this Mexican species, except 
that the elytra are piceous-black. The form is oval-convex, 
and it is easily distinguished by the 4th and 5th dorsal strire 
being abbreviated in front, at about one-fourth from the base. 

67. Acritus saliims, n. sp. -Oblong-convex, shining black, indis- 
tinctly punctured. Prothorax without basal row of punctures. Elytra 
somewhat more distinctly punctured towards the suture, and slightly ru- 
gose behind ; sides smooth. Prostemal striae strongly divergent in front, 
and twice as distant at the lobe as at base ; mesosternum with sub-marginal 
stria entire. Front tibiae moderately dilated, inner margin slightly curved. 
Length .8 mm. ; .032 inch. 

Cedar Keys, found only on the ocean shore. 

68. Ataenius sculptilis Harold, Col. Hefte. iii, 86. 

A species found at Enterprise, agrees in all respects with 
the description of this Venezuelan insect. It is closely re- 
lated to A. cylindrus Horn, but differs by larger size, and by 
the interspaces of the elytra being strongly costate. Length 
4 mm.; .16 inch.

shining, blackish-blue, with metallic gloss. Prothorax with a few scattered 
punctures ; sides much rounded, reflexed margin wider towards the base, 
which is distinctly margined. Elytra with rows of punctures in place of 
the striae ; sutural stria impressed, deeper towards the tip, which is armed 
with a small, acute sutural spine ; side margin broadly flattened and re- 
flexecl near the base, narrower behind. Length about 21 mm.; .83 inch.

Tampa. I have described this species from fragments found 
by Mr. Schwarz. It is mach larger than the other species in 
our fauna, as the elytra of the largest specimen of semi- 
opacits in my collection are 12.5 mm. ; .475 inch long. 

This species seems to have a rather wide distribution in 
the Atlantic States. Dr. C. Zimmermann once told me that 
he had found a large blue Geotrupes, without impressed 
striae, in South Carolina, and if I mistake not I have seen a 
similar specimen from Maryland, in Mr. Ulke's collection. 

70. Diplotaxis laiiguicla. n. sp. — Elongate, sub-cylindrical, pale- 
brown ; head strongly punctured, epistoraa depressed, margin strongly re- 
flexed, broadly truncate in front, angles obtuse and rounded. Prothorax 
about twice as wide as its length, more narrowed in front, less narrowed 
behind, sides with an obtuse, rounded angle just behind the middle ; disc 
strongly punctured. Elytra with the ordinary rows of punctures, inter- 
spaces coarsely and strongly punctured. Front tibiae with two large teeth ; 
claws cleft. Length 6.2 mm. ; .25 inch. 

Tampa ; abundant. 

71. Anomala (Rhombonyx) semilivida, n. sp. — Oval, piceous, 
shining, more or less whitish testaceous above, elytra usually entirely pale. 
Head sparsely punctulate, epistoma pale, concave, rounded in front, mar- 
gin strongly reflexecl. Prothorax twice as wide as long, much narrower 
in front. Sides rounded, very finely margined, base similarly margined ; 
disc sparsely punctulate, with a large transverse dark cloud, sometimes 
occupying nearly the whole surface. Scutellum large, rounded behind, 
dark colored. Elytra with the usual punctured equidistant stria?. First 
interspace wider, with a confused row of punctures from the base to the 
middle ; outer striae somewhat effaced. Legs usually margined with pale ; 
claws simple. Body beneath, thighs and margin of elytra with long hairs. 
Length 6.5 mm.; .25 inch. 

Tampa and Capron. The inner claw of the front tarsi is 
toothed near the base and then suddenly bent, with the lower 
outline slightly sinuate to the tip in four specimens exam- 
ined ; this is probably a sexual mark of the cT, though one 
of the specimens is much stouter in form than the others. 

72. Taplirocerus laevicollis, n. sp. — Very small, slender, convex, 
narrower behind, black-bronzed, shining. Head and prothorax nearly 
smooth, the former large, longitudinally impressed ; the latter with very 
deep oblique impressions towards the sides, which are nearly straight and

Enterprise ; one specimen. Easily recognized by the small 
size, large head, not narrower than the prothorax, and by 
the latter not being narrowed in front. 

73. Nematodes ptinctatus, n. sp. — Elongate, scarcely narrower 
behind, brown, pubescent, strongly punctured. Epistoma at base equal 
in width to the space from it to the eyes. Antennae nearly half as 
long as the body, with the 2d and 4th joints equal, 3d a little longer, 5th 
and 6th still longer, sub-equal ; outer joints longer than wide, equal. Pro- 
thorax wider than long, scarcely narrowed in front, feebly channeled be- 
hind ; strongly and densely punctured. Elytral striae well-impressed, in- 
terspaces strongly punctured, feebly convex towards the base. Beneath 
punctured, last ventral obtusely pointed, and roughly asperate with ele- 
vated granules. Length 5.5 mm.; .'-21 inch. 

Enterprise ; one specimen. A specimen from Texas (Bel- 
frage) agrees in all respects except that the antennae are 
short and less slender, with the 3d joint more evidently 
longer than the 2d or 4th. I am disposed to think the differ- 
ence is sexual. 

74. Aiuhastiis loiigulus, n. sp. — Elongate, pubescent, red-brown, 
elytra and legs paler. Head densely and strongly punctured, front not 
concave, margin fine, not reflexed. Prothorax nearly one-half longer than 
wide, strongly and densely, not coarsely punctured, narrowed in front, 
sides nearly straight, hind angles bicarinate. Elytra with punctured striae, 
interspaces nearly flat, finely not densely punctured. Antennae with 3d 
joint one-half longer than the 2d ; united equal to the 4th. Length 10 mm. ; 
.40 inch. 

Enterprise; one specimen. A smaller specimen (7.2 mm.; 
.29 inch) from Louisiana was given me by Mr. Salle, which 
is a little less elongate, but not otherwise different. 

75. Ancliastus fuscus, n. sp. — Elongate, pubescent, dark fuscous 
above, red-brown beneath. Head coarsely punctured ; punctures umbili- 
cate, front broadly concave. Prothorax coarsely punctured, longer than 
wide, gradually narrowed in front, sides straight, hind angles unicarinate. 
Elytra with coarsely punctured striae, interspaces convex, sparsely and 
finely punctured. Antennae brown, half as long as the body, strongly 
serrate, 2d joint very small, 3d as large as the 4th. Length 7.5 mm.; .30

Cedar Keys, June. 

77. Atliou* clebilis, n. sp. — Small, very elongate, rufo-testaceous, 
pubescent. Head punctured, front not concave, broadly rounded, or sub- 
truncate anteriorly. Prothorax (^) nearly twice as long as wide, slightly nar- 
rower in front, hind angles produced, acute, not carinate, not divaricate ; 
surface densely, rather finely punctured. Elytra with narrow sutural brown 
line, striae deep, interspaces flat, punctulate. Antennae not serrate, half 
as long as the body ; 2d and 3d joints equal, together a little longer than 
the 4th. Length 4.6 mm.; .18 inch. 

Lake Harney, May; one specimen. The 3d joint of the 
tarsi is very distinctly lobed. 

78. Cyplion impressus, n. sp. — Elongate-oval, not convex, piceous, 
pubescent. Antennae and legs piceo -testaceous. Head, prothorax and 
elytra equally densely punctulate, the last without elevated lines ; about 
one-sixth from the base is a strong curved impression extending to the su- 
ture, and behind the middle a still deeper oblique one, not attaining the 
suture ; between these two pairs of impressions the suture is slightly ele- 
vated. Antennae with the 3d joint slender, equal in length to the 2d, not 
shorter than the 4th. Length 2.3 mm. ; .09 inch. 

Tampa, end of April. The impressions of the elytra and 
the suture behind the posterior one are paler and almost 
testaceous. 

79. Iiticidota luteicollis., n. sp. — Elongate, black, pubescent. 
Prothorax bright yellowish-red, sub-triangular, apical angle rounded, 
basal angles sub-acute ; sides oblique, base broadly emarginate, side mar- 
gins depressed and reflexed, more widely towards the base, apex and sides 
scabrous, disc nearly smooth, finely channeled. Scutellum red. Elytra 
finely and densely scabrous, each with two obsolete elevated lines, side 
margin narrow. Antennae (<^) nearly two-thirds as long as the body, 
compressed, joints only slightly narrowed at the base, so that they are very 
feebly serrate. Last two ventral segments rufo-testaceous. Length 8 mm. ;

LucidotcE. L. thoracica from Mexico has been considered as 
identical with P. collaris, but differs by more robust form, 
red scutellum, coarser sculpture, and by the reflexed margin 
of the elytra being much broader. The abdomen of both 
sexes is entirely without phosphorescent organs, and the an- 
tennae are more distinctly serrate than in L. hiteicollis. 

80. Pliofilms (Pyractomena) ecostatus, n. sp. — Elongate, head and 
prothorax pale ; the latter a little longer than wide, rounded on the sides, 
narrower in front, and less broadly rounded at apex, sides depressed, 
scarcely punctured, edge dusky for the greater part of the length ; disc 
finely carinate, with a dark stripe, narrow at the apex, broad at the base, 
which is bisinuate ; hind angles rectangular, blunt at tip. Scutellum dark. 
Elytra finely and densely scabrous, narrowly margined, without discoidal 
elevated lines, sutural, lateral and apical margin pale ; a narrow discoidal 
vitta extends from near the humerus to behind the middle. Antennae dark, 
shorter than the prothorax. Beneath pale, meso- and metathorax, and two 
series of large transverse ventral spots dark ; phosphorescent organs on 5th 
and 6th segments, as two pairs of oval slightly depressed spots of a honey 
yellow color. Legs piceous, trochanters and proximal half of thighs 
pale. Length 14.5 mm.; .57 inch. 

Key West; one ?, Mr. Edw. Burgess. Allied to Ph. 
borealis, but differs by the elytra being more finely scabrous 
and entirely without elevated lines. 

81. Photinus (Pyractosoma) iiitidiventris, n. sp. — Very elon- 
gate, pale. Prothorax with sides broadly flattened, sparsely punctured, 
marked -with an elongate lateral dusky spot, disc with a broad dark dorsal 
stripe. Elytra densely scabrous, without elevated lines, strongly margined ; 
sutural, apical and lateral margins pale ; a narrow dorsal vitta runs from 
near the humerus to bej r ond the middle. Meso- and metathorax fuscous ; ab- 
domen pale ; 2d and 3d segments with a quadrate spot each side half way 
betw T een the median line and the side ; 4th segment with a large transverse 
dark spot each side, remaining segments bright yellow, 5th and 6th each 
with a pair of pits connected with the phosphorescent organs, resembling 
large spiracles. Antenna? shorter than the prothorax, dark, base pale. 
Legs dark, trochanters and base of thighs testaceous. Length 14 mm.; .55 
inch. 

Enterprise ; one cT specimen. The scutellum is testaceous 
and the prothorax rather narrowly rounded at apex ; in 
another specimen from Capron the scutellum is cloudy, and 
the apex of the prothorax is broadly rounded. Nearly allied 
to P. angustata, but in that species the sides of the prothorax 
are not dusky, while the head and the first four ventral seg-

ments are entirely dark. Also nearly allied, but different by 
the densely punctulate phosphorescent segments, is the fol- 
lowing species. 

82. Pliotinus (Pyractosoma) putictiveiitris, n. sp. — Very elon- 
gate, of the same form, size and color as P. nitidiventris, with the sides of 
the prothorax fuscous ; the lst-4th segments of abdomen are not spotted, but 
fuscous, a little paler at the edges. The phosphorescent segments are finely 
and densely punctulate. The discoidal elevated lines of the elytra are dis- 
tinct. Length 13 mm. ; .50 inch.

than wide, sides parallel behind, regularly rounded into the apex before 
the middle, margins widely reflexed, scabrous ; disc sparsely punctulate, 
shining, finely channeled, between the middle and the apex is a transverse 
fuscous spot. Scutellum yellow. Elytra pubescent, coarsely scabrous, 
each with two faint elevated lines ; sutural, apical and lateral margin 
narrowly bordered with yellow, side margin narrow, not reflexed. Beneath 
fusco-piceous, 5th and following ventral segments (<^) yellow, 5th and 6th 
phosphorescent, each with a pair of rounded impressions, having a pore at 
the bottom. Antennae fuscous, not longer than the prothorax. Legs fus- 
cous, anterior and middle more or less testaceous. Length 7.2 mm.; .285 
inch.

84. Pliotinus (Pyractosoma) umbratus, n. sp. — Of the same size, 
form, color and sculpture as P. collustrans, but differs by the prothorax 
having an elongate black spot, extending from near the base to the anterior 
scabrous portion, this spot is wider in front than behind ; the erytra are 
more strongly margined at the side. The antennse are longer and more 
slender, extending beyond the base of the prothorax, and the 1st joint is 
pale. Length 7.5 mm.; .30 inch. 

tf 4th and following ventral segments yellow, 4th and 5th phosphores- 
cent, each with a pair of small pits with a pore at the bottom ; 5th broadly 
emarginate behind, Gth small, emarginate, 7th small, rounded at tip. 

9 The black spot of the prothorax extends to the apex ; the ventral seg- 
ments are black, and only the 4th has a transverse oval phosphorescent 
spot of pale yellow at the middle, the 5th segment is not emarginate, the 
6th is flat, prominent and slightly notched at tip. 

Tampa, Baldwin, Capron ; May and June. Two much 
smaller females seem to indicate other species, which with 
.more material may be properly defined. It seems to me un- 
safe to propose names for them at present. 



LeConte.] 408 [ Feb# 1? 

1st. Capron. 5.5 mm.; .22 inch. The prothomcic black stripe extends 
from the base to the tip ; the scutellum is dark, the 6th ventral segment has 
a small rounded pale yellow phosphorescent spot, besides the large one of 
the 4th segment. 

2d. Cedar Keys. 3.8 mm.; ,15 inch. The prothoracic black stripe ex- 
tends from the base nearly to the tip ; the scutellum is dark, the epipleurae 
are piceo-testaceous, and there is no phosphorescent spot on the 6th 
ventral. 

85. Ozogiiatlms florid a n us 7 n. sp.— Black, shining, scarcely per- 
ceptibly and thinly clothed with very short pubescence, punctulate, an- 
tennae and legs piceous. Prothorax twice as wide as long, convex, sides 
margined, very much rounded, hind angles very small, rectangular, 
slightly prominent. Length 1.4 mm. ; .05 inch. 

Tampa ; two specimens, one of which was most kindly sent 
me by Mr. Schwarz. The sides of the prothorax are very 
much more rounded than in 0. cornutm, and the pubescence 
is much shorter. The c? is not known. 

This is an interesting addition to the genera common to 
Florida or the Antilles and California. 

86. Hemiptychus deoilis, n. sp. — El on gate -oval, convex, red- 
brown, shining, clothed with very fine prostrate pubescence, almost imper- 
ceptibly punctulate. Prothorax short, rounded at base, slightly emargi- 
nate at apex, side angles deflexed, sub-acute when viewed laterally. Elytra 
with two deep striae extending from the middle nearly to the apex. Be- 
neath sparsely, finely punctured with sparse shallow punctures on the sides 
in front of the middle. Antennae and tarsi yellowish. Length 1.9 mm. ; 
.075 inch. 

Enterprise ; one specimen. Resembles H. ventralis, but 
the lateral striae of the elytra are longer, and the surface is 
sparsely covered with shallow punctures at the sides near the 
base ; the form is a little less elongate. 

Hemiptytfuig si mi lis. n. sp.— Elongate-oval, convex, less rounded 
in front than behind, blackish brown, less shining, finely densely punctu- 
late and finely 'pubescent. Prothorax more distinctly punctured towards 
the sides. Elytra with two deep striae extending from the middle to near 
the tip ; punctures more distinct at the sides and in front. Beneath finely 
punctulate. Length 2.3 mm. ; .09 inch. 

Tampa ; one specimen. 

87. Henriptj elms abtoreviatus, n. sp.— Oval, convex, equally 
rounded before and behind, dark-brown, with a slight reddish tinge, im-

punctulate, strire two, deep, beginning about, one-fourth from the apex ; 
the outer one meets a very short trace of the sutural stria ; the inner one is 
shorter than the outer one. Under surface scarcely perceptibly punctulate. 
Length 2.0 mm.; .08.") inch. 

Capron ; one specimen. Easily known by the short striae, 
and very fine pubescence. 

88. Hemiptyclms auctus, n. sp. — More elongate-oval, convex, 
equally rounded before and behind, sub-opaque, indistinctly punctulate, 
reddish-brown, densely clothed with short, yellowish pubescence. Elytra 
with the outer stria beginning just behind the middle, joining a short rem- 
»nant of the sutural stria ; 2d stria beginning farther back, and joining a 

trace of the sub-sutural stria inside of the 2d stria; beginning at the middle, 
and running backwards for a short distance is an indistinct 3d stria, in the 
direction of which is situated a large granule. Beneath indistinctly punc- 
tulate. Length 1.5 mm. ; .06 inch. 

Capron ; one specimen. I do not observe anything similar 
to the granule, or elevated puncture above mentioned in any 
other species. It is situated about one-fifth from the apex. 

The species of Hemiptychus here described are to be iuca- 
lated in the table (Proc. Acad. Nat. Sc. Phila. 1865, 239), 
between H. ventralis and obsoletus. Several other species al- 
lied to H. gravis, are indicated in the collections of Dr. Horn 
and myself, but until larger series of specimens are obtained, 
I think it is undesirable to describe them. 

89. Catorama punctulata, n. sp, — Elongate-oval, convex, black- 
ish-fuscous, rather shining, thinly clothed with fine, prostrate, very short 
pubescence, distinctly but finely punctured. Beneath similarly punctured, 
antennae and front tarsi yellow-brown. Length 2.5 mm.; .10 inch. 

Tampa ; one specimen. The pubescence has a sericeous re- 
flection, where it is well preserved. 

90. Catorama liolosericea^ n. sp. — Elongate-oval, convex, fus- 
cous, densely clothed with short, gray, erect hair, producing a velvet sil- 
very lustre ; elytra each with a large, oblique spot about the middle, and 
a smaller round posterior one without lustre, and consequently appearing 
darker ; surface imperceptibly punctulate. Length 1.5 mm.; .06 inch.

bust than the others, and is easily known by the very small 
size, and fine though not indistinct punctures. 

The following species from California and Texas may be 
conveniently described at the present time. 

92. Catorama frontalis, n. sp. — Sub-cylindrical, rounded at each 
end, brown, somewhat shining, very fmel} r and densely punctulate, clothed 
with fine, short, sericeous pubescence. Head with the curved frontal im- 
pression deep, side margin of front stronger than in the other species, 
and narrowly reflexed. Prothorax with the hairs so arranged as to give 
the appearance of a slight elevation at the middle of the base. Length 4.2- 
6 mm.; .17-.25 inch. 

Santa Barbara ; one specimen, collected by Mr. Gr. R. Crotch. 
Of the same size, form, color and sculpture as C. simplex, but 
differs by the sericeous pubescence, and more strongly mar- 
gined front. On comparison, the sides of the elytra are seen 
to be more broadly and distinctly concave, but this differ- 
ence is not very obvious. 

Catorama sectans, n. sp. — Elongate-oval, convex, blackish, clothed 
with extremely fine brown pubescence, distinctly punctulate. Elytra with 
the punctures towards the sides arranged somewhat in rows, and with in- 
distinct traces of two stria? near the base. Beneath distinctly punctured, 
antenna? yellow-brown. Length 3.3 mm. ; .13 inch. 

Texas; Dr. Horn. Very like C. panctulata, but larger, with 
the line punctures of the elytra arranged in rows near the 
sides and with slight traces of the two outer stria? near the 
base, thus showing a tendency towards Hemiptychus. 

93. Catorama otosoleta, n. sp. — Elongate-oval, convex, brown, 
imperceptibly punctulate and finely pubescent. Elytra with some feeble 
traces of striae at the sides, especially near the base. Length 2.4— o.o mm. ; 
.10-. 13 inch. 

Southern part of California; one specimen collected by 
Mr. Hardy was kindly given me by Dr. D. Sharp. This 
species is very similar to C. punctalata, but is of a browner 
color, and not distinctly punctulate.

and much smaller. 

93. Dorcatoma tristriatnm., n. sp. — Oval convex, less rounded in 
front, shining, black, thinly clothed with short, sub-erect gray pubescence. 
Hard and prothorax finely punctulate. Elytra finely, densely punctured, 
with three striae near the side ; these striae begin in front of the middle, the 
outer two extend nearly to the tip, while the 3d is much shorter, ending 
about one-fourth from the tip. Beneath finely punctured (antennae not 
seen). Length 2.5 mm.; .10 inch. 

Bosque County, Texas; Mr. G. W. Belfrage, one specimen. 

96. Caenocara lateralis, n. sp — Broadly ovate, convex, black, 
shining, sparsely and finely punctured, pubescence gray, sparse, erect. 
Prothorax more densely punctured towards the sides. Elytra with 1st and 
2d striae deep, entire ; the 3d extends from the base for one-third the length ; 
the lateral lobe has a distinct marginal stria. Beneath strongly punctured. 
Length 1.5 mm.; .06 inch. 

Enterprise ; one specimen. This species closely resembles 
the small form of C. oculata, in shape, color, and sculpture, 
but differs by the lateral lobe of the elytra, which has a 
distinct marginal stria. The eyes, as in C. oculata, are almost 
divided by a narrow acute emargination. The antennse are 
yellow-brown. 

97. Caenocara intermedia, n. sp. — Ovate, convex, brownish- 
black, shining, finely sparsely pubescent. Head finely punctulate, emar- 
gination of the eyes rounded at the end, less deep. Prothorax finely punc- 
tulate. Elytra finely punctulate in rows ; lateral lobe faintly striate ; outer 
stria entire, deep, 2d stria deep from the base for three- fourths the length,

North Carolina ; Dr. Zimmermann, one specimen. This 

species resembles Dorcatoma in the sculpture, but the form is 

more robust, and the eyes emarginate to near the middle. 

98. Caenocara calif ornica, n. sp.— Broadly ovate, convex, black, 
shining, with fine sparse sub-erect hairs. Head and prothorax rather 
densety punctulate. Elytra less densely punctulate, with three stria? near 
the sides ; 1st and 2d entire, 3d beginning at the base and extending one- 
third the length ; there is no marginal stria. Beneath finely punctured

R1RRHODES, nov. gen. (Anobiini.) 

Body rounded, slightly oval, convex, pubescent with coarse hairs. Head 
inflexed, broad, mandibles resting against the metasternum in repose ; un- 

der surface . Antennae 10-jointed ; 1st joint large, auriculate, 2d nodose, 

rather large, attenuated at base, 3d slender, 4th and 7th subtransverse, 
gradually slightly wider (4th appears to be indistinctly impressed trans- 
versely); 8th triaugular, as long as the whole stem, from the 2d to the 7th ; 
about twice as wide as long, remaining joints broken. Palpi not seen. 
Eyes not convex, not emarginate, partly covered behind by the prothorax. 
Presternum not seen, front coxa? deeply sunk in the cavity, not seen. 
Mesosternum concealed by the metasternum, which is produced in front 
into a broad square process, the anterior margin of which is slightly 
rounded, and the front angles are acutely prominent laterally. The pos- 



1878. ^'* [LeConte. 

terior part of the metasternum is large, sparsely punctured, with a median 
impressed line, each side of which is a shallow round impression. Legs 
slender, rather long, middle coxae separated by the metasternal pro< 

middle legs received in transverse excavations, which extend on the epi- 
pleurae ; hind legs received in excavations which occupy the whole of the 
length of the 1st ventral segment, and extend to, but not upon, the edge 
of the elytra ; tarsi broad, 1st joint not elongate. 5th not narrower nor 
longer than the 4th; claws small, divaricate, appendiculate, ventral seg- 
ments 5, as usual ; 1st short, occupied by the excavations for the hind legs ; 
2d, 3d and 4th equal, each about twice as long as the 1st ; 5th nearly as 
long as the two preceding, broadly rounded ; the sutures are equalty plain 
and straight. Elytra striate. 

This genus is allied to Dorcatoma and Ccenocara, but differs 
from both by the elytra being striate, by the 2d joint of the 
antennae being larger, and by the form of the metasternal 
process which is much narrowed at base in Dorcatoma, and 
very short in Ccenocara. Having seen but one specimen, I 
am unwilling to risk it by an attempt to expose the pres- 
ternum, especially as the genus is very well characterized 
without reference to that part. 

99. Byrrhodes setosus, n. sp. — Robust, oval, convex, obliquely nar- 
rowed in front, blackish-brown (somewdiat shining where the hair is re- 
moved), densely clothed with coarse white curled hairs, very finely and 
densely punctulate. Head with a transverse frontal impressed line near 
the margin ; sides obliquely margined. Prothorax short, of the same form 
as in Ccenocara, outline when viewed from above oblique. Scutellum flat, 
rounded. Elytra with well impressed striae, the two outer ones deeper be- 
hind the middle ; interspaces wide, flat, the outer ones slightly convex be- 
hind ; lateral edge finely margined from base to tip. Beneath nearly 
smooth, very sparsely punctulate. Sterna glabrous (by abrasion ?), abdo- 
men hairy. Length 3.5 mm. ; .14 inch. 

Capron; one specimen. On superficial view, this insect 

might be readily mistaken for a small species of Byrrhus. 

100. Elaphidium tectum, n. sp. -Elongate, slender, brown, clothed 
with short fine rather dense dirt colored pubescence, scarcely mottled on 
the elytra. Antennae (rj 1 ) as long as the body, joints 3-10 each with a 
spine at the inner apical margin ; the spine of the 3d is about one-fourth 
as long as the 4th joint, the others diminish gradually in length ; the outer 
apical angle of the joints 5-7 is also armed with a small spine. Prothorax 
a little wider than long, moderately rounded on the sides, densely punc- 
tured, with a smooth dorsal line more distinct behind the middle, and a 
discoidal round callus each side in front of the middle ; on the deflexed 
sides near the base are seen a few large round punctures or foveae. Elytra

coarsely not densely punctured, punctures smaller towards the tips, which 
are bispinous, the outer spine much longer than the sutural. Thighs of 
the hind legs with a short spine on the inner side. Length 15.6 mm. ; 
.63 inch. 

Cedar Keys; two c?. This species is related to E. mucro- 
natum and incertum, but the antennae are not longer than the 
body, and the pubescence is more uniform ; the punctures of 
the elytra are also more distant. It seems to resemble E. la- 
natum Chevr. (Am. Ent. Soc. Fr. 1862, 260) from Cuba, and 
I should consider it as the other sex of the same species, ex- 
cept that the outer angle of the 3d and 4th joints is not 
armed with a spine.

with gray hair. Elvira flattened on the disc, hind third of surface smoky- 
brown, limited in front by a curved blackish line, concave forwards ; this 
line is angulated about the middle of the width, then again concave for- 
wards, and joins a lateral narrow black line, which is dilated behind the 
humerus; asperities black, sparse, small, arranged in distant rows ; tips 
strongly and obliquely truncate, outer angle prominent ; punctures coarse, 
rather densely placed. Prothorax without discoidal inequalities, nearly 
twice as wide as long, sides oblique from apex to beyond the middle, where 
they are distinctly angulated, then narrowed to the base ; there is a small 
black spot extending from the base to the lateral angle. Beneath brown, 
finely pubescent, not mottled, legs scarcely mottled ; antenna 1 a little longer 
than the body, punctured and annulated. Length 8 mm.; .32 inch. 

Tampa; one specimen. A very distinct species. The 1st 
joint of the hind tarsi is as long as the two following, and 
the lateral angle of the prothorax is obtuse, not rounded, but 
also not prominent, and is distinctly nearer the base than the 
apex, while in all the others in our fauna it is at the middle 
of the side, and obtusely rounded. It might be properly 
referred to Sternidius, but in that genus the lateral angle of 
the prothorax is more prominent. Until another revision 
of this division of CemmbycidcB is made, I prefer to place this 
-species in Leptostylus, rather than to establish it as a separate 
ofenus. 



1878. 410 [LeConte. 

ZAPLOUS, n. g. (CerambtciDuB, subf. Laxliidm.) 

Body small, not very robust, clothed with prostrate, short pubescence. 

Head rather short, not channeled, support of labrum coriaceous, eyes rather 
coarsely granulated, deeply emarginate, upper part much smaller than the 
lower. Antenna 1 a little shorter than the body, 11 jointed, with very few 
flying hairs on the lower edge; 1st joint long, slender, slightly clavate 
(very much as in Leptostylus, Liopus &c); 2d joint cylindrical, nearly one 
third as long as the 1st ; 3d and 4th elongate, together equal to the remaining 
ones united, which gradually diminish in length, but not in thickness. 
Prothorax wider than long, not tuberculate, sides rounded, sometimes in- 
distinctly angulated ; front coxal cavities widely angulated. Elytra wider 
than the prothorax, parallel, humeri well rounded, tips rounded, not trun- 
cate. Front coxa prominent, narrowly separated, middle coxse more widely 
separated, cavities open externally. Legs short, thighs stout, but not cla- 
vate ; front tibiae with inner groove feeble ; middle tibiae with a slight 
but distinct tubercle on outer margin. Tarsi short, not slender, 1st joint 
scarcely longer than 2d ; last joint long, claws divaricate. 

The small insect which indicates this genus belongs to the 
tribe Pogonocherini (Lee. Class. Col. JS. Am. 340), but does 
not fit well into any of the groups thus far known in our 
fauna.* 

103 Zaplous HulVbardi, n. sp. — Brown, clothed with short, pros- 
trate yellowish-gray pubescence, somewhat mottled by unequal distribu- 
tion. Prothorax very densely, rather finely punctured. Elytra more 
strongly and less densely punctured. Antennae annulated with black, 
finely punctulate and pubescent, without mixture of large punctures. 
Length 3.3-5 mm.; .13-.20 inch. 

Enterprise; frequently beaten from old vines, in May. 

104. Donacia rugosa, n. sp. — Coppery-bronze, not shining, rugose, 
rather robust, sub-depressed. Head channeled in front, line deeper behind, 
and ceasing betw r een the ej^es ; eyes convex, prominent, orbits wide. Pro- 
thorax quadrate, a little wider iu front, where the angles are well-marked, 
sides not sinuate ; surface densely rugose and punctured, dorsal line widely 
impressed but vague, feebfy, transversely impressed near the base. Elytra 
obliquely narrowed towards the tips, wdiichare truncate ; discoidal impres- 
sions vague, the 1st small, near the scutellum ; the 2d large, in front of the 
middle ; the 3d small, near the suture, and behind the middle ; stria com- 
posed of elongate punctures, interspaces densely, transversely rugose. Be- 
neath dark plumbeous, w T ith fine, pruinose pubescence. Hind thighs ( 9 ) 
not toothed, antenna slender, three-fourths as long as the body, blackish. 
Length 9.2 mm. ; .37 inch.

more slender. 

105. Dialjrotica vincta, n. sp.— Black, protliorax bright yellow, 
quadrate, smooth, with two large discoiclal fovea?, side margin narrowly 
reflexed. Elytra wider than protliorax, punctured somewhat in rows, with 
the lateral and apical border, and a narrow vitta from the base to the tip, 
occupying an elevated ridge parallel with the suture, pale yellow. Beneath 
yellow, meso- and metathorax, outer half of thighs, tibia? and tarsi black. 
Antenna? black, base brownish ; 3d joint longer than 2d, united equal to 
the 4th. Length 4 mm. ; .16 inch. 

Capron ; April, one specimen. 

106. €Edionycliis indigoptera, n. sp.— Dull ferruginous, anten- 
na? and legs piceous ; elytra bine -black, strongly and densely punctured, 
narrowly margined. Head sparsely punctured, median line abbreviated 
in front, and interrupted at the vertex ; there are two small rounded fovea? 
between the eyes. Prothorax transverse, narrowed in front, sub-sinuate, 
but scarcely rounded on the sides, which are broadly flattened ; front angles 
small, prominent ; disc smooth, not shining. Hind thighs very large, finely 
and sparsely punctured. Length 3 mm. ; .12 inch. 

Tampa; one specimen. The 5th ventral segment is widely 
concave at the tip. This species is not closely allied to any 
other known to me in onr fauna ; the middle tibiae are angu- 
late on the outer margin as in (E. thyamoides Crotch. 

106. Argopistes scyrtoides. n. sp.— Circular, not very convex, 
rufous, extremity of hind thighs, and the upper surface black, shining. 
Head brown. Prothorax very short, deeply emarginate in front, rounded 
at base, finely punctulate ; a curved, transverse, rufous band extends from 
the base each side, near the hind angles ; the sides are also rufous. Elytra 
scarcely perceptibly punctulate, marked with distant stria? composed 
of extremely fine punctures ; each with a large, triangular, rufous spot, 
with the apex in front, extending to the suture behind the middle. Length 
3.4 mm.; .135 inch. 

Florida ; two specimens given me by Mr. Ulke. The re- 
semblance of this insect to a small Exochomus is marvellous. 
The genus is also remarkablefor having occurred thus far only 
in north-eastern Asia. The mesosternum is entirely con- 
cealed between the pro- and metasternum, and the latter is 
very short. The hind thighs are immensely large in propor- 
tion to the size of the insect. Though the next species has 
not occurred as yet in Florida, its geographical distribution 
renders its appearance there very probable.

North Carolina and Texas. I have adopted the manuscript 
specific name given by Dr. Zimmermann. This is the first 
introduction of the genus into the literature of our fauna; 
Sphceroderma insolita Mels. is the type of CerataUiea Crotch, 
and belongs in another group. 

108. Cliaetocnema pinguiSj n. sp. — Sub-ovate, convex, more 
pointed behind ; coppery bronze, not very shining, base of antennae, tibiae

with fine punctured stria, interspaces flat, smooth. Sides of last ventral 
segment finely punctured. Length 2.2 mm. ; .09 inch. 

Enterprise and New Smyrna, two specimens. Very like 
C. denticulata, but more pointed behind; the sculpture is 
much finer and the last ventral segment is not coarsely and 
sparsely punctured, but is nearly smooth at the middle and 
finely punctured towards the sides.

California, Grilroy ; one specimen, Mr. GT. R. Crotch. The 
antennae are broken and but two basal joints remain. 

112. Chaetociieiua flavicornis, n. sp. — Oval, convex, dark 
bronze, not very shining, antennas yellow, scarcely darker at the outer ex-

punctured, narrowed in front of the middle, post apical angle distinct ; 
there is also a basal puncture each side opposite the base of the 6th stria. 
Elytral striae composed of small, close-set punctures, interspaces obsoletely 
punctulate. Length 1.4 mm. ; .055 inch. 

Detroit, Michigan ; one specimen. Easily known by the 

small size, robust form and yellow antennae. The legs are 

dark, and the ventral segments sparsely punctured. The 

obliquely cut front angles of the prothorax and the basal 

puncture indicate a tendency toward Crepidodera. 

113. Chaetocnema ooesula, n. sp. — Still smaller, oval, convex, 
black bronzed, not very shining, antennae and legs dark. Head smooth, 
with the usual impressions. Prothorax transverse, sides oblique, narrowed

this character, added to the convex form of body, and the 
absence of elytral stride, would require the separation of this 
insect as a distinct genus. 

DIGNAMPTUS, n. g. Tenebeionid/E ; Heterotarsini. 

Body elongate, resembling Stenochia. Head short, eyes large, trans- 
verse, coarsely granulated. Antennae as long as the head and prothorax, 
rather slender. 3d joint a little longer than the 4th ; 8th, 9th and 10th 
wider and larger, scarcely as long as wide, 11th longer, oval. Palpi with 
the last joint strongly securiform, mentum obovate, transverse, with two 
shallow impressions. Prothorax sub-cylindrical, slightly rounded and sub- 
sinuate on the sides, which are narrowly margined, hind angles small, acute, 
or rectangular. Elytra a little wider than the prothorax sub-cylindrical, 
humeri not prominent, stria? composed of large close punctures, interspaces 
narrow. Epipleurae narrow, not reaching the tip, impinged upon by the 
4th and 5th ventral segments, which are rounded at the sides. Legs long, 
slender ; tarsi with the 1-3 of the front and middle pair broad, and the 
1st and 2d of the hind pair less dilated, brush-like beneath ; penultimate 
joint small, last joint as long as the others united, claws large, simple. 

118. Dignamptus stenocliinus, n. sp. — Elongate, shining black, 
with a bluish gloss. Head densely punctured. Prothorax more strongly 
punctured, one-half longer than wide, sub-sinuate on the sides behind the 
middle ; hind angles small, acute, prominent. Elytra with striae of very 
coarse punctures ; interspaces narrow, smooth. Flanks of prothorax 
coarsely, meso- and metasternum sparsely punctured. Abdomen sparsely 
rinely punctured. Length 7. ram.; .28 inch. 

Enterprise ; June, beaten from dead vines ; very rare. Has 
very much the appearance of a small Stenochia. 

119. Dignamptus langurinus, n. sp. — Linear-elongate, black, 
with a slight metallic gloss. Antennas stouter, more strongly and more 
gradually thickened externally, the 6th and 7th joints being wider than the 
preceding, though not so wide as the following. Head rinely punctured. 
Prothorax strongly punctured, one-half longer than wide, slightly narrower 
behind, hind angles rectangular, not prominent. Elytra slightly wider 
than the prothorax, striae composed of oval punctures, in distance equal to 
their long diameters , interspaces wider than the striae, flat, smooth. Be- 
neath as in the preceding. Length 4 mm.; 16 inch. 

Enterprise; May, very rare. This species has much the 
appearance of a Languria, and the more thickened antennae 
tend to increase the resemblance. 

120. Phaleria punctipes, n. sp. — Oval, convex, black, or piceous, 
sometimes testaceous above but without spots. Prothorax narrow T ed in 
front, rounded on the sides, especially near the apex, base finely margined,

with a large, basal puncture each side. Elytra finely striate, interspaces 
wide, flat, smooth. Under surface towards the sides very finely scabro- 
punctulate. Legs black, front thighs nearly smooth, middle and hind thighs 
coarsely and sparsely punctured ; tibiae densely punctured. Length 7 mm, 
. 28 inch. 

Haulover ; abundant on the ocean shore. Larger and stouter 
than P. testacea, and easily known by the black and coarsely 
punctured legs. In this respect it resembles P. pilifera from 
Lower California, from which it differs only by the epipleurse 
being smooth and glabrous, while in P. pilifera they are punc- 
tured and setose. 

'121. Platydema crenatum, n. sp. — Oval, rather elongate, con- 
vex, black, shining. Head punctured in front, transverse impression 
faint. Prothorax sparsely, finely punctulate, base bisinuate, not margined, 
each side with a broad, shallow impression. Elytra with deep, very 
coarsely punctured striae. Beneath punctured, last two ventral segments 
nearly smooth. Antennas, palpi and tarsi brown ; prosternum convex be- 
tween the coxae, point inflexed, not prominent. Length 4.5 mm.; .18 inch. 

Haulover ; one specimen. More convex than P. Icevipes, 
and very distinct by the coarsely punctured elytral striae. 

122. Hypoplilreus glatoer, n. sp.— Cylindrical, red-brown, shining, 
with erect hairs. Head densely and finely punctured, transverse line 
well-impressed. Prothorax longer than wide, convex, finely punctured, 
sides nearly straight, finely margined, front angles not prominent, almost 
rounded. Elytra finely, rather densely punctured. Pygidium equally, 
densely, finely punctured. Abdomen less densely punctured, 5th ventral 
segment vague, impressed Length 3 mm.; .12 inch. 

Tampa; two specimens, also found in Georgia, under pine 
bark. This species is smaller, narrower and more convex 
than H. parallelus, and differs by the front angles of the 
prothorax not being acute and prominent. It has the same 
form as H. thoracicus and piliger, but differs by the elytra 
being more finely punctured, without erect hairs, and by the 
pygidium being not sparsely but densely punctured. 

I do not find mentioned in any work that the 3d, 4th and 
5th ventral segments in this genus are longitudinally, deeply 
impressed near the sides, so that the margin appears to be 
thickened. 

123. Hypophlceus piliger, n. sp. — Slender, cylindrical, convex, 
red-brown, shining. Head punctured, transverse line obsolete, front with 



1878.] 42d [LeConto. 

a shallow, rounded impression between the eyes. Prothorax longer than 
wide, sides slightly rounded, near the apex and base, hind angles rectangu- 
lar, rounded at the extreme tip, finely not densely punctured, with a few 
erect hairs towards the sides, base not margined. Elytra finely not densely 
punctured, punctures here and there, forming rows (but not indicating 
striae) ; there are some erect hairs, especially near the tip, and at the sides. 
Pygidium sparsely punctured. Beneath punctured, last ventral segment 
not impressed. Length 2.5 mm.; .10 inch. 

Florida, Georgia and South Carolina ; under pine bark. I 
have adopted the name which it bears in the collection of 
Dr. Zimmermann. This species is more slender than H. par- 
allelus, and differs by the sparse, erect hairs, by the punctures 
of the elytra being less fine and more distant, and by the 
pygidium being sparsely punctured. In these respects it 
agrees with H. thoracicus, but differs in color, and by having 
fewer erect hairs. 

Three new species remain in my collection, which may be 
described on the present occasion ; the subjoined table gives 
the essential characters of all the species in our fauna. 

124. Hypo pill tie us su"bstriatus, n. sp. — Very dark brown, cylin- 
drical, less convex than the other species. Head punctured, transverse line 
well impressed, vertex with a faint, transverse impression, anterior to 
which the surface is more convex. Prothorax scarcely longer than wide, 
punctured, side margin stronger than in the other species, base margined. 
Elytra rather strongly punctured, punctures in rows except near the sides 
and tips, without hairs. Pygidium densely, finely punctured. Beneath 
punctured ; last ventral segment broadly impressed, apical part convex. 
Length 4.2 mm. ; .18 inch. 

Oregon ; collected by Lord Walsingham. Much larger 
than H. parallelus, and easily distinguished by the less con- 
vex form, more strongly margined prothorax, and by the 
elytral punctures being stronger, and placed in rows. 

125. Hypophloeus opaculus, n. sp. — Cylindrical, convex, black- 
ish, not shining. Head feebly punctulate, transverse line bounded behind 
by an obtuse, transverse ridge ; epistome convex. Prothorax a little wider 
than long, sides broadly rounded, apex not eniarginate, sides very finely 
margined, base indistinctly margined, surface finely, rather densely punc- 
tured. Elytra finely punctured, punctures here and there in rows. Py- 
gidium densely, finely punctured. Beneath sparsely punctured ; 5th ven- 
tral with a small, apical tubercle. Length 3.2 mm.; .13 inch. 

Southern California; one specimen collected by Mr. Hardy,

ridge of the head causes the clypeal impression to appear 
very deep. 

126. Hypoplilociis tenuis, n. sp. — Very slender, cylindrical, con- 
vex, red-brown, shining, antennae and legs ferruginous. Head sparsely 
punctulate, transverse impression deep. Prothorax one third longer than 
wide, front and hind angles rounded at the extreme tip ; apex not emargi- 
nate, sides very finely margined, base indistinctly margined, surface 
sparsely punctulate. Elytra punctured, with indications of stria? behind 
the middle, and near the suture. Pygidium sparsely punctured. Beneath 
sparsely punctulate ; 5th ventral segment more strongly punctured, not im- 
pressed. Length 2.2 mm. ; .09 inch.

becomes acutely triangular ; the humeral region is dull ferruginous. I am 
unwilling to describe it as distinct, but regard it rather as a well-marked 
variety. 



LeConte.] 428 [ Fefti 1? 

Though not belonging to the same zoological province, the 
two following species may be conveniently described here : 

133. Morclella jovialis, n. sp. — Black, pubescent, with the mar- 
gins of the prothorax cinereous pubescent. Elytra densely cinereous pub- 
escent with black markings as follows : two small spots near the 
base, the outer one elongate, the inner one round ; a transverse 
broad band at the middle, divided by a cinerous sutural line, the 
anterior outline of this band is nicked outside of the middle, and 
then runs obliquely forwards, almost to the side margin, which is 
cinereous ; the apical fourth is also black, divided almost to the 
tip by the cinereous sutural line. Beneath thinly clothed with pruinose 
cinereous pubescence, ventral transverse bands and hind coxa? blackish. 
Length 4.7 mm.; .19 inch. 

Bosque County, Texas, G. W. Bel f rage ; one specimen. 
Of the same form and size as M. oculata, to which it is allied. 

134. Mordella obliqua. n. sp. — Black, pubescent. Head 
cinereous, prothorax with scattered cinereous hairs, and two 
indistinct vittae more densely cinereous. Elytra with a very 
narrow sutural line, and an oblique stripe from the humeri to 
beyond the middle, where it becomes obsolete, cinereous. Scu- 
tellum cinereous. Beneath black ; anal process long and slen- 
der. Length 4 mm.; .16 inch. t 

Maryland, Dr. Zimmermann; Detroit, Michigan, Mr. E. 
A. Schwarz. In form and size this species resembles 31. 
marginata. It is possible that M. lunulata Helmuth (Proc. 
Ac. Xat. Sc. Phila. 1865, 98), may have been a specimen of 
this species, with the elytral vitta partly effaced. The type 
has, I believe, been destroyed. 

135. Conotraclielus ventralis, n. sp.— Not robust ; elytra nar- 
rowed behind from the base, humeri not dentiform. Blackish-brown, 
thinly clothed, but scarcely mottled with coarse pale yellowish hairs. 
Beak half as long as the body, slender, brown, shining, sparsely punc- 
tured, striate each side for more than one-half the length. Antenna? in- 
serted about one-third from the tip. Head strongly punctured, pubescent. 
Prothorax as long as wide, widest at the base, gradually narrowed and 
slightly rounded on the sides to the apex, near which it is feebly con- 
stricted ; very deeply, coarsely and densely punctured, elevated dorsal 
line very narrow, indistinct. Elytra at base about one- half wider than 
the prothorax, humeri rounded, acutely margined, prominent, sides ob- 
liquely converging behind ; fully one-half longer than the width at base, 
striate composed of large fovea?, interspaces not costate at base, but the 
3d and 5th become gradually acute behind the middle ; 7th acute for the

whole length, united in front at a sharp angle with the 9th, which is also 
acute tor its whole length, the two united then form the humeral margin. 
Beneath, intlexed flanks of prothorax densely, metathorax more coarsely 
but sparsely eribrate ; ventral segments very shining, with a few scattered 
large punctures, more numerous on the 5th. Legs long, thighs strongly 
unidentate, not annulat . Length 6 mm.; .25 inch. 

Enterprise ; one specimen. Quite different from any other 
in our fauna; it should be placed after G. cratcegi, (vide Lee. 
and Horn, Rhynch., 230), between 1-Ba and 1-Bb. 

136. Conotraclielus cognatus, n. sp. — Blackish ; elytra mottled 
with dull fulvous ; pubescence short, irregularly condensed. Head punc- 
tured, pubescent. Beak not half as long as the body, rather slender, very 
slightly curved, not shining, strongly striate. Antennas inserted less than 
one-fourth from the tip. Prothorax wider than long, sides strongly 
rounded in front, nearly straight near the base ; constricted near the apex ; 
very coarsely and densely eribrate, not carinate. Elytra one-half wider 
than the prothorax at the base, oblong, rounded behind, humeri rounded ; 
strise composed of large quadrate punctures, interspaces narrow, not fiat, 
3d, 5th and 7th acutely but not strongly costate ; 9th acute from the 
middle to within a short distance from the tip ; at the base of the 3d inter- 
space is a small spot of white scales. Beneath, mesosternum prominent, 
metasternum eribrate ; ventral segments sparsely, 5th more densely punc- 
tured, impressed near the tip. Legs long, thighs unidentate, with a ring 
of gray pubescence. Length 4.3 mm.; .17 inch. 

Tampa; one specimen. This species has the mesosternum 
produced into a small process in front, as in C. posticatus, 
from which it differs chiefly by the prothorax being not 
carinated, and by the somewhat less robust form. 

137. Conotraclieliis pusillus, n. sp. — Similar to the preceding, but 
very much smaller, blackish -brown, with irregularly condensed pubescence ; 
elytra mottled with dull fulvous. Head punctured, yellow pubescent ; 
beak longer than head and prothorax, stout, curved, deeply striate. An- 
tennas inserted one-fourth from the end, brown. Prothorax wider than 
long, rounded on the sides, broadly constricted near the apex, densely and 
coarsely punctured, not carinate. Elytra nearly one-half wider than the 
prothorax at base, oblong-oval, humeri rounded ; strise composed of large 
punctures, interspaces not so narrow as in C. cognatus, 3d, 5th and 7th 
moderately carinate ; 9th carinate behind the middle. Beneath coarsely punc- 
tured ; 5th ventral broadly impressed, mesosternum protuberant. Legs 
long, thighs unidentate, obsoletely annulated. Length 2.5 mm.; .10 inch. 

Enterprise ; one specimen. This is one of our smallest 
species.

138. Conotractielus coronatus, n. sp. — Blackish, thinly clothed 
with very fine brownish-gray pubescence and scattered pale clavate bristles, 
with markings of dense fine white scales. Prothorax and elytra tubercu- 
late ; the former as long as wide, channeled, rough, with the sides straight, 
angulated and sudclenh^ narrowed near the apex; there are four large 
apical tuberosities, and two discoidal ones, besides the lateral protuberance 
just mentioned ; the anterior constriction is very deep and there is also a 
transverse impression behind the lateral and discoidal tuberosities ; a narrow 
white vitta extends from apex to base each side mid-way between the dor- 
sal channel and the sides ; these lines are connected with others on the 
base of the 3d elytral interspace. Elytra sub-triangular, humeri prominent, 
rounded. Striae composed of large punctures, interspaces wide, alternately 
interrupted with black tubercles bearing reclinate clavate bristles ; at the 
base of the 3d interspace is a short white line ; a large marginal spot, pointed 
interiorly behind the humerus, is also clothed with dense small white 
scales ; behind the middle is a band composed of four small spots on the 
1st to the 4th interspaces, and a small spot near the tip formed of pale 
scales. Legs long, thighs indistinctly annulated and sprinkled with white 
hairs, acutely unidentate. Under surface very coarsely punctured. Length 
3 mm. ; .12 inch. 

Enterprise ; one specimen. The head is coarsely cribrate ; 
the beak bent beyond the middle, not longer than the head 
and prothorax, thicker than in any other species known to 
me, with deep broad stria?, and carinate along the median 
line. Antenna? situated near the end. The mesosternum is 
protuberant. This species belongs to Division II, of my 
arrangement, and should be placed before G. tuberosus, (Lee. 
Rhjmch., 233), to which (apart from coloration) it has little 
resemblance. The femoral denticle is obsolete, but the tooth 
is acute and prominent. 

139. Acalles ventrosus, n. sp.— Very obese, blackish, clothed 
with appressed gray and brown scales with intermixed clavate bristles. 
Head with the occiput clothed with yellowish-gray scales. Prothorax 
deeply and broadly channeled, twice as wide as long, rounded on the sides, 
uniform blackish brown. Elytra truncate at base, basal angles obtuse not 
rounded, sides obliquely widened, then rounded obliquely to the apex; 
there is a broad basal band occupying one-third the length of dirty gray 
scales, and some indistinct fasciate markings of the same color, behind the 
middle ; the striae are deeply impressed, and the interspaces moderately 
convex. Mesosternum broadly emarginate, as in A. pectoralis (Lee. 
Rhynch., 244). Legs clothed with dirt-colored scales. Length 4.3 mm.; 
.17 inch. 

Enterprise ; May, one specimen. More ventricose than

any other species in my collection, and easily known by the 
deeply and broadly sulcate prothorax ; the anterior trans- 
verse impression is broad and deep, and there is a broad dis- 
coidal impression each side near the base. 

140. lea lies sii bliispidus, n. sp. — Blackish, densely clothed with 
dark scales, which are larger on the prothorax than on the elytra, where 
they are intermixed with short, reclinate bristles. Prothorax wide, strongly 
rounded on the sides in front, coarsely punctured, with a narrow, lateral 
line, and a few scattered scales pale dirt color ; disc not carinate. Elytra 
but little wider than the prothorax, base truncate, basal angles obtuse, dis- 
tinct, sides broadly rounded, then obliquely narrowed to the apex ; very 
little wider behind the base, striae coarsely punctured, interspaces slightly 
convex ; there are traces of two narrow undulated bands, composed of 
small spots of gray scales, one before the middle, curving backwards 
towards the sides, the other behind the middle, curving forwards. Mesos- 
ternum deeply emarginate. Length 3.7 mm.; .15 inch. 

Sumter County ; May, one specimen. Easily known from 
our other species by the shorter reclinate bristles of the 
elytra. The prothorax is larger, and the elytra less rounded 
on the sides. 

141. Cryptorhynclius helvus, n. sp.— Very similar to ft obliquus 
and differing only in the following characters : Scales pale yellow- brown, 
slightly variegated with darker ; form of body a little narrower. Prothorax 
a little longer than wide, sides obliquely narrowed from the middle, where 
they are rounded to the apex, nearly parallel behind the middle. Elytra 
with the interspaces wide and flat. Thighs with one small acute tooth. 
Length 7.8 mm.; .81 inch. 

Enterprise ; May, one specimen. Except for the difference 
in the form of the prothorax, I should consider this as 
merely a variety of C. obliquus. The elytra are similarly im- 
pressed. 

142. Barilepton toivittatutm, n. sp. — Very elongate, black, 
shining, with a broad vitta of white scales each side, beginning at the front 
margin of the prothorax, and extending to the tip of the elytra. Head 
sparsely and finely punctured, beak curved, not as long as the prothorax, 
smooth. Prothorax wider than long, narrowed and rounded on the sides 
near the apex, where it is broadly and feebly constricted ; disc strongly, 
not densely punctured, with an indistinct, narrow, smooth median line. 
Elytra with impunctured striae, interspaces wide, flat, feebly and very 
finety punctulate. Beneath sparsely punctured ; there is a patch of white 
scales on the flanks of the prothorax ; the side pieces of the metasternum, 
and the sides of the ventral segments are also clothed with white scales ;

Georgia and Northern Florida. For a specimen of this 
very handsome species, I am indebted to Dr. Horn. 

143. Sphenopliorus apicalis, n. sp. — Elongate, black, not 
shining. Prothorax with a narrow dorsal elevated line extending to 
the apex, where there is a large, oblong fovea on each side of it ; discoidal 
elevations not apparent ; punctures very large, shallow, irregularly scat- 
tered. Elytra with fine striae, upon which are placed large, distant, 
rounded punctures ; alternate interspaces slightly more convex near the 
base* which is deeply bifoveate, or trifoveate each side. Length 7 mm.; 
.2j inch. 

Enterprise; May, one specimen. Belongs to Dr. Horn's 
Group V, (Proc. Am. Phil. Soc. 1873, 421), and may be 
placed in the table after S. Sayi, to which it is not allied. 
The proximal third of the beak is deeply and broadly exca- 
vated. The 3d joint of all the tarsi is narrow, and not 
spongy beneath. 

144. Mesites rufipeiitiis, n. sp. — Elongate, cylindrical, shining 
black, glabrous, antennae and legs brown, elytra ferruginous. Head and 
dilated base of beak sparsely punctured, the former with a large, vertical 
fovea, the latter with a short, deep channel. Prothorax longer than wide, 
oblong, a little narrower in front, sides broadly rounded, more so at base 
and apex ; surface strongly but not densely punctured. Elytra with striae 
composed of approximate square punctures, interspaces not wider than the 
striae, sparsely punctulate, the small punctures generally forming an 
irregular series on each interspace. Beneath coarsely punctured, ventral 
segments 1-4 sparsely and less coarsely punctured. Length 5.3 mm.; .21 
inch. 

9 Beak slender, smooth ; antennae inserted just in front of the eyes. $ 
unknown. 

Xew Smyrna ; one specimen found on the ocean beach. 
This species is quite congeneric with M. subcylindricus, but 
differs by the red elytra, and more finely punctulate inter- 
spaces. The funiculus of the antennse is stout, 7-jointed, 
and the 2d joint is not elongated. I therefore infer that 
they belong to the genus Mesites as restricted by Mr. Wol las- 
ton, and heretofore known only from Europe. 

145. Pityophthoriis obliquus, n. sp. — Cylindrical, not slender, 
dark-brown, shining, thinly clothed with fine, long, erect pubescence ; an- 
tennae and legs ferruginous. Head flat, opaque, indistinctly punctulate. 



l' > ' ) [LeConte. 

Prothorax quadrate, scarcely longer than wide, broadly rounded at apex, 
anterior one fourth covered with obtuse granules, not arranged in concen- 
tric lines, gradually changing behind into fine, rugose, sparse punctua- 
tion. Elytra finely punctured, punctures arranged in approximate rows, 
which in places are indistinct ; apical declivity flattened, feebly concave each 
side of the sutural stria, which is not very distinct ; there are also traces at 
the apex of two other stria?. Front and middle tibia? not toothed ; hind 
tibia 1 with a marginal row of 7 or 8 small acute spines, and a fringe of stiff 
long hairs. Length 2 mm. ; .08 inch. 

Enterprise; June, one specimen. This species may be 
placed after P. digestus Lee. (vide Rhynch. 352), but the flat- 
tened declivity of the elytra, Only slightly concave near 
the suture, easily distinguishes it from all thus far described 
in our fauna. The punctures of the hinder part of the elytra 
are less fine than towards the base. The eyes are emargi- 
nate; the club of the antennae is nearly circular, and trans- 
versely annulated. 

146. Pityophthorus seriatus, n. sp. — Elongate, cylindrical, 
brown, shining, nearly glabrous, with only a few scattered, erect hairs on 
the head, front of prothorax, and hind part of elytra Antenna? and legs 
testaceous. Head flat, opaque, indistinctly punctulate, front feebly im- 
pressed, and indistinctly carinate. Prothorax quadrate, not longer than 
wide, rounded in front, anterior half with irregular, transverse, subconcen- 
tric rows of granules ; sides and base sparsely but distinctly punctured. 
Elytra with stria? composed of small punctures, interspaces wider than the 
stria?, the alternate ones each with 4 or 5 distinct punctures of equal size 
with those of the stria? ; declivity not flattened nor refuse, sutural stria 
slightly impressed. Length 1.5 mm. ; .06 inch. 

Tampa; April, one specimen. This species is quite dis- 
tinct by the sculpture of the elytra, and may be placed be- 
fore P. contains, in the arrangement already cited. The 
front and middle tibiae are not serrate, and the hind tibiae 
have only 3 or 4 very indistinct traces of teeth, and no range 
of spines, or fringe of stiff hairs as in P. obliquus. This 
species has a deceptive resemblance to Xyleborus pubescens, 
but the generic characters of the antennal club are quite 
different, and the specific characters abundantly distinct. 

147. Cryphalus miles^ n. sp. — Very small, slender cylindrical, 
blackish, shining, clothed with short stout erect bristles. Prothorax a lit- 
tle longer than wide, apex produced into an acute spine ; disc with a few 
acute reclinate granules in front, sparsely punctured behind. Elytra

antennae piceous. Length .8 mm.; .035 inch. 

Tampa ; two specimens. Smaller and more slender than 

C. rigidus Lee. (Rhynch. 362), with much shorter bristles. 

The apical spine of the prothorax is a prolongation of the 

margin itself, and not a horn arising from the disc. 

148. Eiixenus piceus, n. sp. — Oval, rather elongate, convex, piceous, 
shining. Prothorax sparsely punctulate. Elytra punctured, the punctures 
forming indistinct striae towards the sides ; two outer stria? distinct, the 
outermost extending from the base for one-third the length ; the inner one 
entire; marginal stria entire. Length .6 mm.; .025 inch. 

Tampa, April 11th ; one specimen. Differs from En. 
punctatus Lee. (Rhynch. 409), by the much smaller size, less 
distinctly punctured prothorax, and by the legs being not 
testaceous but dark, with only the tarsi yellowish. This in- 
sect has the appearance of a very minute Crytocephalus.

Remarks on Geographical Distribution. 
By John L. LeConte, M.D. 

In now concluding this, the most complete faunal list of insects which 
has been prepared in the United States, it may be proper to make a few 
remarks on the subject of geographical distribution as exhibited by the 
Coleoptera above enumerated. Any observations now offered, must be very 
imperfect, and subject to large corrections when the faunal lists of the Cole- 
optera of other parts of the country have been prepared with equal care and 
industry. 

The total number of species contained in the list (exclusive of Aleocha- 
rini, not yet studied) is 1457. 

Of these the following are also found in the Antilles : (18?), 17. 

Cicindela tortuosa (Mex., S. Am., Dicrepidius ramicornis (S. Am.).

Dacoderus, one species in Arizona ; another in San Domingo. 



1878. J 471 [LeConte, 

And also these relations with more distant regions : 
Argopistes ; Florida and North Eastern Asia. 
Onota ; Florida and South America. 
Brachypeplus (section); Florida and Africa. 
Mesites ; Florida, Delaware and Europe. 
Stenoscelis ; Southern States and Cape of Good Hope. 



A remarkable feature in the geographical distribution, as exhibited by 
this list of Coleoptera is the comparatively small number of species common 
to Florida and the Antilles. A little reflection on the geological develop- 
ment of Florida, and its relation to the Gulf Stream will show the reason 
for this apparent anomaly. 

The Peninsula of Florida has extended southward during comparatively 
modern times by the gradual growth of coral reefs and their subsequent 
conversion into land surface ; this surface would naturally be occupied by 
the insects and plants living in the conterminous northern regions, as far as 
they were able to endure the approach to a tropical climate. On the other 
hand the Gulf Stream, more and more compressed by the narrowing of the 
strait between Florida and Cuba, would have a tendency to interrupt all 
transfer of living beings from the Island to the Continent ; while the 
passage of species from the coast of Mexico and Northern South America 
to either Florida or the Antilles would be slightly facilitated. 

The occurrence of Sosylus and Dacoderus, in the deserts near the Pacific 
coast and in San Domingo must be referred to a much older condition of 
things, when the connections of land surface were quite different from that 
of the present time ; and in fact the characters of the genera indicate that 
they are old forms. Sosylus is a Colydiide related somewhat to the Aus- 
tralian and North American Derataplirus; while Dacoderus differs from 
every other Tenebrionicle by the front coxse being contiguous.

The Coleoptera of Michigan. 

By H. G. Hubbard and E. A. Schwahz. 

(Bead before the American Philosophical Society, April ISth, 1878.) 

1. Descriptions of New Species by John L. LeConte, M.D. 

I have written these descriptions in order that fewer species without 
names may be referred to in the two lists which form the bulk of the 
present memoir. 

The lists of the Coleoptera of the Upper and Lower Peninsulas of Michi- 
gan respectively, have been prepared by the authors with great care, after 
extensive explorations and collections in the two regions. The species, as 
far as described, have been identified with the series contained in my col- 
lection, and I cannot sufficiently express my thanks, to both Mr. Hubbard 
and Mr. Schwarz, for the great liberality with which they have given me 
even unique specimens, so that all the material necessary for comparison 
and investigation is placed in one single collection. My series, therefore, 
both of Florida and Michigan Coleoptera, contain all the species cata- 
logued in their lists, and a basis for future studies in geographical distribu- 
tion has been thus firmly established. 

I have added to the list of the species from Lake Superior all those col- 
lected in my own extensive explorations of that basin, which were not 
contained in the collections of the authors. This list is therefore to be 
considered as a complete catalogue of the Coleopterous fauna of that 
region, so far as at present known, and exhibits some very interesting- 
points in geographical distribution. 

Especially worthy of notice is the large proportion of species common 
to Lake Superior and Alaska, and if types of the other species described by 
Mannerheim and Maklin were accessible for comparison, the number of 
forms in this category could doubtless be still farther increased. Space and 
time alike forbid my making a separate list of such species on the present 
occasion, but I intend to recur to the subject again, when larger series from 
the Alpine heights of the Rocky Mountains have been collected. The oc- 
currence at Lake Superior of Euthia scitula and Syntomium confragosum, 
previously known only from Alaska, and Gonotropis gibbosa from Colorado, 
deserves mention ; as also the extension northward of Gallida smamgdina. 

1. Dyscliirius "brevispinus. Shining black, feebly bronzed, rather 
robust, antennae, palpi, and legs rufous. Epistoma very slightly emarginate, 
angles not prominent, transverse impression deep, frontal impressions also 
deep. Prothorax longer than wide, oval, a little wider behind ; lateral mar- 
gin extremely fine, scarcely continued behind the posterior lateral punc- 
ture. Elytra oval, as wide as the prothorax, brownish at the tip, base not 
margined ; striae uniformly abbreviated in front, very coarsely punctured, 
obliterated a little behind the middle, 8th represented at the tip by a short 
groove ; scutellar puncture large ; dorsal punctures two, one on the 3d in- 
terspace near the base, the 2d near the 2d stria about the middle. Front

LeConte.l Jtl [April IS, 

tibiae not toothed on the outer edge, terminal digitation long, slender, 
curved ; spur not longer than the first joint of the tarsus. Length 3.4 mm. ; 
.135 inch. 

Detroit ; one specimen. This species is very distinct by 
the small size of the lower spur of the front tibiae, and ma} T 
be placed as a separate division in B, A, a, of my table 
(Proc. Ac. Fat. Soc. Phila. 1857, 76.) before sphcericollis. 

2. Badister obtusiis. Piceous, shining ; prothorax, base of antennas, 
palpi and legs testaceous ; elytra piceo-testaceous, lateral margin and base 
testaceous. Prothorax wider than long, narrower behind, hind angles 
rounded, indistinct, side margin not wider towards the base, which is not 
explanate towards the sides, basal impressions rounded, not extended to- 
wards the sides ; dorsal line deep, transverse impressions feeble. Elytra 
with well-marked strioe, interspaces nearly flat, 3d with two dorsal punc- 
tures contiguous to the 2d stria, Length 5.8 mm. ; .23 inch. 

Marquette, Lake Superior ; one specimen. More allied to 
the Californian B. ferrvgineus than to any other in my col- 
lection, but easily known by the more rounded hind angles 
of the prothorax. 

3. Renibicliuni (Notaphus) arcuatum. Black, with a greenish 
bronzed lustre. Antennal scape, palpi and legs piceo-testaceous. Elytra 
piceous, with ill-defined testaceous markings, viz. : a humeral cloud, lateral 
narrow margin, curved band behind the middle, which is concave back- 
wards, and apex ; epipleuree black and testaceous. Prothorax wider than 
long, rounded on the sides, strongly sinuate behind, base as wide as the 
apex , hind angles rectangular, carinate ; basal impressions deep, dorsal 
line well-impressed, transverse impressions feeble. Elytra elongate-oval, 
humeri rounded, striae distinctly punctured to behind the middle, then finer 
and smoother ; 8th stria deep near the tip ; dorsal punctures two, on the 3d 
interspace. Length 5.4 mm.; .21 inch. 

Marquette, Lake Superior. This species resembles B. flam- 
mulatum of Europe, but is wider and less convex. It also 
greatly resembles B. incrematum Lee. from Cala., Oregon and 
Alaska, but the latter has the elytral markings undefined, 
and the striae finer and less strongly punctured. 

4. Bemtodium (Notaphus) versutum. Beneath black, shining ; 
above bronzed ; bead and prothorax not polished ; antenna? piceous, base, 
palpi and legs testaceous. Prothorax wider than long, narrowed behind, 
sides rounded in front, strongly sinuate behind, base not narrower than the 
apex ; basal angles rectangular, carinate, basal impression rugose, deep ; 
dorsal line abbreviated at each end, transverse impressions obsolete. Ely- 
tra elongate-oval, wider than the prothorax, humeri rounded, angles slightly 
marked ; striae entire, fine, finely punctulate to behind the middle, inter- 



1878.1 5 J5 [LeConte. 

spaces flat, 3d with two dorsal punctures ; color brown with metallic lus- 
tre, with large ill-defined testaceous markings arranged as in B.indistinc- 
tum, epipleurse testaceous edged with black. Length 4.3 mm.; .17 inch. 

Marquette, Lake Superior. Smaller and less convex than 
the preceding, with the prothorax wider and not polished. 
This species resembles the Californian B. approxirnatum and 
indistinctum in form and markings, but differs by the sides 
of the prothorax more strongly sinuate towards the base, 
and by the head and prothorax being less shining, and of a 
brown-bronze, not green-bronze color. 

5. Hydro poms fuscatus Crotch. Oblong-oval, elongate, pointed 
behind, shining brown above, mottled with darker ; antennse with the 
outer joints blackish. Prothorax slightly rounded on the sides finely and 
distinctly punctured, basal plica extending a short distance upon the ely- 
tra, which are more strongly and not densely punctured. Metasternum 
with a few scattered punctures, and three strire behind. Length 1.7 mm.; 
.065 inch. 

Detroit and Lake Superior. Allied to affinis, but the elytra 
are more strongly and sparsely punctured ; the continuation 
of the stria upon the elytra is very short, and forms an angle 
with the thoracic stria. Among 14 specimens examined I 
find no sexual difference worthy of note, and I have redes- 
cribed this species in order to correct an error made by Mr. 
Crotch, who (Trans. Am. Ent. Soc. 1873, 391,) considered as 
the 9 a different species, in which the stria is not continued 
upon the elytra. 

6. Hydroporus laccopliiliims. Ovate, depressed, pointed be- 
hind, brown, paler in front, darker behind ; epistoma not margined, head 
finely punctulate ; prothorax ((^) rugose and finely punctured, narrower in 
front, sides oblique, finely margined. Elytra (J 1 ) strongly punctured, 
shining, ( 9 ) opaque, finely sparsely punctulate. Metasternum channeled 
for the posterior half of its length ; sparsely punctured in front ; abdomen 
coarsely punctured in both sexes. Length 2.6 mm. ; .10 inch. 

Detroit ; rare. The form is exactly that of a Laccophilus 
in miniature. The head and prothorax of the 9 are opaque 
and very finely and sparsely punctulate. 

7. Supliis semipunctatus. Elongate-oval, not pointed behind, 
moderately convex, yellow-brown, shining, smooth ; elytra darker, covered 
from the middle to the tip with scattered coarse punctures ; of which one 
series extends to thejbase half way between the margin and suture. Pros- 



LeCoute.] 5 JO [April 18, 

ternum not punctured, less dilated behind than in the other species, but 
with two short posterior striae ; nietasternurn with a deep impressed 
median line, smooth, with only a few scattered punctures behind. Length 
26 mm. ; .10 inch. 

Monroe, Michigan ; one specimen ; very different from the 
other species by the regularly oval form, scarcely narrower 
behind than before, by the peculiar punctuation of the elytra 
and by the impunctured sterna. The last joint of the maxil- 
lary palpi is nearly acute at tip, and does not appear emar- 
ginate from any point of view. 

The insect mentioned in the Florida list (ante p. 438) as 
Suphis n. sp., on remounting, proves to be a very small 
species of Laccophilus, having the same form of presternum 
as the others. It may be here conveniently described as : 

8. Laccopliilus pumilio. Ovate, pointed behind, not convex, im- 
punctured, rufo-testaceous, meso- and metasternum darker; elytra piceous, 
slightly iridescent, regularly narrowed behind, and not obliquely truncate 
at tip ; abdomen without the distant fine oblique lines seen in the other 
species. Length 1.9 mm. ; .075 inch. 

Enterprise, Florida ; one specimen. Very careful exami- 
nation shows in certain lights traces of two or three lines on 
the second ventral segment towards the sides, but these are 
the only evidences of the characteristic ventral sculpture of 
the other species. 

9. Gaurodytes leptapsis. $ Elongate-oval, less obtuse than usual, 
black, with a slight bronzed tint, opaque, finely strigose with lines forming 
very elongate meshes ; base of antennae, palpi, front and middle legs tinged 
with piceous. Head less opaque than the prothorax, the sides of the latter 
are oblique, finely margined and scarcely rounded. Elytra with the usual 
rows of punctures indistinct. Beneath shining, finely reticulate, meso- 
sternum acutely emarginate, hind tibiae sparsely, coarsely punctured, mar- 
gined on the inner side, but without a very distinct row of punctures. 
Front and middle thighs distinctly, not densely punctured. Length 9.7 
mm. ; .38 inch. 

Marquette, Lake Superior ; one specimen. This species is 
as elongate as G. parallelus, but less obtusely rounded, and 
is easily recognized by the peculiarily elongated meshes of 
the reticulation. The presternum is obtusely carinate. 

10. Gaurodytes loiigulus. Elongate-oval, obtuse at each end, not 
convex, shining, smooth black, with a slight metallic gloss. Antennae, palpi 



1878.] 597 [LeConte. 

and feet tinged with piceous. Prothorax with sides oblique, finely mar- 
gined ; apical and basal rows of punctures strongly marked. Elytra with 
the rows of punctures strongly marked. Prosternum acutely carinate ; me- 
sosternum deeply emarginate ; front and middle thighs punctured and ru- 
gose ; hind tibia: smooth, with a few small punctures at the inner margin 
and some larger ones along the outer margin. Length 9 mm. ; 35 inch. 

(^ Smooth but not polished ; claws of front tarsi long, not toothed, curv- 
ed on]y near the tip. 

9 Scarcely perceptibly punctulate ; claws of front tarsi not so long, and 
regularly curved. 

Lake Superior ; the elytra vary from brown to black, with 
only the edge brownish. The form is exactly as in Gr. 
parallehis, from which it differs greatly by the other charac- 
ters. 

11. HydroMus feminalis. Sub-ovate, convex, blackish piceous, 
sides of prothorax and elytra and beneath paler. Head and prothorax 
sparsely punctulate, elytra finely not densely punctured, sutural stria deep, 
extending from the middle to the tip. Length 2 mm. ; .08 inch. 

Detroit. This species is less oval than the others of the 
same size in our fauna, and is somewhat narrower behind 
than in front ; it is free from metallic lustre. The pros- 
ternum and mesosternum are not prominent, and the thighs 
are punctulate and pubescent from the base nearly to the 
knees. It therefore belongs to the genuine Hydrobii, and is 
allied to the two following Californian species. 

12. HydroMus castaneus. Oval, convex, shining brown, beneath 
piceous. Head prothorax and elytra finely, moderately densely punctured, 
the latter a little more strongly ; sutural stria deep, extending from the mid- 
dle to the tip. Length 2.5 mm. ; .10 inch. 

Lake Tahoe, Cal. ; Mr. Crotch. The pro- and mesoster- 
num are not carinated, and the thighs are punctulate and 
pubescent except near the knees. 

13. HydroMus cuspidatus. Oval, more elongate and somewhat 
less convex ; blackish piceous, paler at the sides of the head and prothorax, 
also along the basal and apical margins of the latter ; finely punctured, 
rather more strongly upon the elytra, with here and there indistinct traces 
of rows. Length 3.4 mm. ; .14 inch. 

Lake Tahoe, Cal. ; Mr. Crotch. The prosternum is not 
carinate ; the mesosternum is strongly carinate, with the an- 
terior angle rectangular and slightly cuspidate. The under 



LeConte.l 5j® [April 18, 

surface and thighs are punctulate and pubescent almost to the 
knees. 

14. Halbrocerus? magims. Elongate, depressed, blackish piceous. 

Head and protkorax shining, polished, the former with one frontal punc- 
ture each side. Prothorax twice as wide as long, emarginate at tip, broad- 
ly rounded at base, narrowed in front, strongly rounded on the sides, basal 
angles much rounded ; sides finely margined, with two marginal punctures, 
and one in the base near the angle, base very finely margined ; disc with one 
setigerous dorsal puncture each side. Elytra finely punctured and pubes- 
cent, with some feeble traces of striae near the base towards the suture. 
Dorsal segments densely punctulate. Beneath finely punctured and pu- 
bescent ; tip of abdomen, antenna?, palpi and legs piceous. Length 3.8 mm. ; 
.15 inch. 

tf 6th ventral segment acutely emarginate, 7th more deeply emarginate 
almost to the base, 8th prominent, rounded at tip. 

9 Ventral segments not emarginate. 

Isle Royale, Lake Superior. This species differs from 
H. Schwarzi by the much greater size, more elongate and 
depressed body, and pubescent elytra ; it seems to be a con- 
necting form between this genus and Tachinus. 

15. Agatliidiuni globatile. Black, shining, completely contrac- 
tile into a ball. Head and prothorax smooth. Elytra smooth, without 
sutural stria, fine]}* margined, margin extending along the base almost to 
the scutellum, which is large and triangular. Length (when contracted) 2 
mm.; .08 inch. 

Marquette and Detroit. Much smaller than A. oniscoides, 
but not otherwise specially different. 

16. Agatliidiiim parviilum. Hemispherical, not contractile, 
rufo-piceous, shining, smooth, elytra with sutural stria extending from the 
middle to the apex. ■ Length 1.2 mm. ; .05 inch. 

Marquette, Lake Superior. This is the smallest species 
in my collection, and is less contractile than any other known 
to me. 

17. Stapliyliims caesareus Cederholm; Er. Staph. 378. 

A specimen of this European species, found at Detroit, 
differs by having the golden pubescence confined to the 
neck and to the posterior margin of the second dorsal seg- 
ment. No golden hairs are visible either at the base and 
apex of the prothorax or on the sides of the ventral segments. 

18. IJatrisus simplex. Rufous, shining, sparsely pubescent. Head 



1878.] OJJ [LeConte. 

slightly scabrous, vertex slightly elevated and convex, surrounded by a 
shallow curved impression. Prothorax carnpanulate, with the dorsal and 
lateral stria 1 deep ; behind the middle between the stria) each side is an 
acute conical tubercle, and still nearer the base two very small teeth. Ely- 
tra indistinctly and sparsely punctulate. Antennae with the joints 3-8 not 
longer than wide, 9th and 10th rounded gradually larger, 11th still larger, 
oval, pointed. Hind tibia? with long terminal spur. Length 2 mm.; .08 
inch. 

cP Head finely scarbrous, front protuberant anteriorly and retuse, with 
an apical concavity. 

9 Head nearly smooth, vertex entirely smooth, front gradually decliv- 
ous not prominent. 

Detroit ; one pair. Sufficiently distinct by the feeble sculp- 
ture of the head, and the absence of antennal sexual char- 
acters. 

19. Ortlioperus scutellaris. Oblong-oval, slightly convex, pic- 
eous, black, glabrous, not very shining. Scutellum large, very distinct. 
Elytra narrowly margined behind with testaceous. Length .7 mm.; .027 
inch. 

Michipicoton River, north shore of Lake Superior ; also 
found in Illinois, and abundantly in British Columbia, at 
Lake Labache. This species is double the size of 0. glaber, 
and less rounded. It is recognized at once by the very dis- 
tinct scutellum. 

Under a high magnifying power the elytra are seen to be 
finely strigose, and very sparsely and indistinctly punctulate. 

20. Orthoperus suturalis. Oval, rounded, slightly convex, pice- 
ous black, glabrous, shining. Scutellum distinct. Elytra with a very fine 
sutural stria slightly visible from the middle to the tip. Length .5 mm. ; 
.02 inch. 

Enterprise, Florida. Smaller, or of the same size and 
form as 0. glaber, but easily known by the distinct 
scutellum, and fine sutural stria. The elytra are very 
sparsely and indistinctly punctulate as in the preceding. 

21. Ortlioperus elongatus. Oblong-elongate, slightly convex, 
piceous, moderately shining. Scutellum distinct. Elytra with a very 
fine sutural stria effaced behind, but curving in front around the base and 
ending half way between the scutellum and the humerus ; tips separately 
rounded, with the apex of the abodomen more prominent than in the 
other species. Length .5 mm. ; .02 inch. 



LeConte.J ^00 [April 18, 

Tampa, Florida. Smaller and narrower than the other 
species, having much the form of Ptilium. 

22. Latliridius opaciilus. Elongate, blackish piceous, opaque. 
Antennae one-half longer than the head. Prothorax slightly convex, wider 
than long, a little narrowed behind, sides rounded in front, subsinuate 
behind the middle, margin not reflexecl ; disc transversely impressed near 
the base. Elytra elongate-oval, one-fourth wider than the prothorax, striae 
fine punctulate, interspaces flat, disc oblique and broadly impressed in front 
of the middle ; sutural stria more deeply impressed behind the middle. 
Length 1.5 mm. ; .06 inch. 

Detroit, Illinois, Mass., and Maryland. In some speci- 
mens the prothorax is obsoletely channeled. 

23. Latliridius maculatiis. Less elongate, blackish piceous, 
opaque. Head and prothorax broadly channeled, the latter feebly convex, 
wider than long, narrowed behind, sides finely serrate, not refiexed, 
rounded in front, sinuate towards the base ; disc deepry transversely im- 
pressed behind the middle. Elytra nearly one-half wider than the pro- 
thorax, truncate at base, widest just behind the middle, sub-depressed, striae 
fine, punctured, sutural and two outer ones deeper, especial^ near the tip; 
color testaceous, tessellated with black quadrate spots, margin blackish; 
disc deeply obliquely impressed near the base. Length 1.9 mm.; .075 
inch. 

Detroit. Allied to these two species is the following : 

24. I, at hi id ins tluplicatus. Moderately elongate, blackish pice- 
ous, opaque. Prothorax one-halt' wider than long, narrowed behind, sides 
finely serrate, rounded in front, oblique behind, hind angles obtuse ; disc 
feebty impressed in front of the middle, and with a shallow transverse im- 
pression behind the middle. Elytra one-third wider than the prothorax, 
elongate-oval, striae composed of punctures, not regularly arranged, and 
approximated by pairs ; the sutural and two outer ones are slightly im- 
pressed near the tip. Legs rufo-piceous. Length 1.9 mm. ; .075 inch. 

Illinois, and Detroit. This and the two preceding species 
belong to the group JEnicmus Thomson, in which the pres- 
ternum extends to the hind margin of the prothorax, the an- 
tennae are shorter than the head and prothorax, with the 
three outer joints enlarged ; and the prothorax is not strong- 
ly margined at the sides. 

In L. sculptilis only two joints of the antennae form the club ; it thus 
belongs to Coninomus Thomson. In L. Uratus, a still more remarkable 
peculiarit} r , first mentioned to me by Dr. Horn, is seen ; the presternum 
extends only a short distance behind the coxae, and is enclosed by the 
epimera, which coalesce on the median line as in Khynchophora ; the front 



1878.] uOl [LeConte. 

coxa? are also conical, prominent and contiguous. The antennas are slen- 
der and longer than the head and thorax, as in the true Lathridii with cos- 
tate prothorax. These differences in structure entitle it to be ranked as a 
distinct genus for which the name Step7iostet7ms may be adopted. 

The two following species belong to Enicmas, though the 
antennas are more slender and a little longer than in those 
above described, and the sides of the prothorax are flattened. 

25. Latliridius teiiuicornis. Robust, depressed, dark brown, 
head and prothorax opaque, scabrous, slightly channeled. Prothorax more 
than one-half longer than wide, narrowed before and behind, sides strongly 
rounded, oblique towards the base, margin finely serrate, flattened but not 
reflexed ; disc with a transverse slightly curved impression in front of the 
base, extending nearly to the sides. Elytra oval, wider than the prothorax, 
strongly margined, impressed near the base, shining ; stria? scarcely impress- 
ed, finely punctured, interspaces flat, each with an obsolete row of very 
fine points. Antennas shorter than the head and>prothorax, slender, three 
outer joints longer, but very slightly thickened. Length 2 mm.; .08 inch. 

California, near Sonoma. 

26. Latliridius laticollis. Less robust, sub depressed, brown, an- 
tennas, legs and antennas rufous. Head and prothorax opaque, scabrous, 
feebly channeled, the latter nearly twice as wide as long, formed and 
sculptured as in 'L. tenuicomis, but less rounded on the sides. Elytra 
elongate- oval, very little wider than the prothorax, truncate at base, 
strongly margined at the sides, slightly impressed near the base ; strias 
punctured, scarcely impressed, fainter behind ; interspaces nearly smooth, 
flat. Antennas two-thirds as long as the head and prothorax, slender, 
outer three joints a little thickened. Length 1.5 mm. ; .06 inch. 

Detroit. This species is very closely related to L. tenui- 
comis, and differs only by the prothorax being less rounded 
on the sides, and the elytra but little wider than it. 

ODONTOSPHItfDUS nov. gen. Sphindid^:. 

General characters as in Sp7iindus, except : 

Body elongate, glabrous ; sides of the prothorax but feebby rounded, 
with 6 or 7 distinct teeth ; elytra with strias not impressed but .strongly 
punctured. Flanks of prothorax not concave for the reception of the an- 
tennas. Antennas, legs, tarsi and sterna precisely as in SpMndus. 

This genus would seem to indicate a relation between the families Sphin-

stria long ; behind the base there is a shallow impression. Antenna? paler 
at base, club large, two-jointed ; e} r es convex prominent. Length 2.7 mm. ;

other specimens from Canada and California. 

EURYSPHIXOUS nov.gen. Sphindidje. 
General characters as in Sphindus, except : 

Body broadly oval, moderately convex, clothed with erect hairs ; pro- 
thorax narrowed in front, rounded on the sides ; elytra with striae feebly 
impressed, strongly punctured. Flanks of prothorax deeply and widely- 
concave beneath. Eyes small, frontal suture finely impressed, not deep. 

28. E. Itirtus. Blackish brown, shining, pubescent with stiff erect 
hairs. Head sparsely punctulate, frontal suture fine, e} T es small, not promi- 
nent, but convex. Prothorax more than twice as wide as its length, nar- 
rowed in front, sides slightly flattened, edge acute, crenulate, scarcely mar- 
gined, base sub-sinuate not margined, disc strongly not coarsely punctured. 
Scutellum large, finely punctured. Elytra with striae of well marked 
punctures, interspaces feebly convex, rugosely punctulate ; humeral callus 
rather prominent, paler brown. Beneath punctured, tibiae and tarsi paler. 
Length 1.6 mm. ; .00 inch. 

Detroit ; one specimen. In the Munich Catalogue Sphindus is 
placed at the end of the Ptinidce, a position for which it is unsuit- 
ed, on account of the much smaller coxal cavities the pres- 
ternum distinctly separates the coxae, which are themselves, 
though transverse, small and not prominent. The form of 
the antennae and tarsi also forbids a reference to the 
Ptinidae. To these characters I have to mention, that the 
antennae, in repose, are Hexed in a different manner, the 
slender part being laid each side along the prosternal suture, 
and the club bent suddenly outwards, behind the front leg. 
In Eurysphindus the flanks of the prothorax are deeply con- 
cave for the reception of these organs, in Sphindus the con- 
cavity is much less ; and in Od.ontosphindus the depression is 
obsolete, though the form of the antennae is the same in all 
three genera. I may here observe that the club of the an- 
tennae is described as three-jointed ; the 8th joint is so much

smaller than the 9th and 10th, and moreover, so little differ- 
ent in width and length from the 7th, that it seems more 
natural to view it as belonging rather to the stem than to 
the club, which would thus be properly designated as two- 
jointed. 

M1CETOPHAGIS Hellw.* 

The species known to cfccur in our fauna are eleven in number, three 
of which will now for the first time be described, two of these presenting 
characters worthy of special mention. 

M* confusiis departs remarkably in sculpture from the other species, 
to a degree that one of the generic characteristics becomes lost. There is 
no arrangement of punctures in striae except very feebly at middle near 
the base, while the punctures of the intervals become so numerous and 
large that the punctuation becomes confused as in Tripliyllus, 

M. tenuifasciatus has a peculiar male sexual character, consisting 
of a transverse row of fine silken hairs on the first abdominal segment. 
No other species in our fauna has any other male character than that af- 
forded by the anterior tarsi which are three-jointed, in the female four- 
jointed. 

In the vast majority of our species the antenna? are either somewhat fu- 
siform or gradually thickened to tip ; two, however, have the last three 
joints of equal width and rather suddenly wider than the preceding. Other 
characters of less importance are made use of in the following synoptic 
table.

1. Antennas gradually broader externally or sub-fusiform 2.

3. Abdomen moderately shining, punctuation less dense : 

Presternum coarsely punctured. Antennas longer than head and 
thorax punctatus. 

Prosternum nearly smooth. Antennas not longer than head and 

thorax californicus. 

Abdomen densely and finely punctured, sub -opaque. 

Prosternum nearly smooth at middle flexuosus. 

Prosternum densely and coarsely punctured bipustulatus.

4. Margin of thorax entire : 

Form rather broad, thorax densely and freely punctured 

pluriguttatus. 
Form slender, thorax coarsely and deeply punctured Melsheimeri. 
Margin of thorax serrulate : 

Elytra maculate with yellow spots pluripunctatus. 

Elytra piceous brown pini. 

5. Elytra nearly black. Male with brush of hair on first ventral 

tenuifasciatus, n. sp. 

Elytra piceous, maculate with yellow. Male without brush 

obsoletus, n. sp. 

6. Elytra maculate with large yellow spots confusus, n. sp. 

With Melsheimeri I have united obscurm, the latter seeming to be 

merely an unicolorous form. M. pini and pluripunctatus would seem to 
occupy the above relationship, but the latter is always more slender and 
less depressed. 

Of the above species calif ornicus and pluriguttatus are peculiar to Cali- 
fornia, confusus to Colorado, tenuifasciatus extends across the north of our 
territory, while the other species are widely distributed in the Atlantic and 
Gulf States. 

29. Jlycetopliagus californicus Horn, n. sp. Oval, piceous, fee- 
bly shining, sparsely clothed with brownish pubescence. Head moderately 
densely punctate. Antennae brownish, base and terminal joint paler, the 
latter nearly as long as the two preceding. Thorax transverse, broadest 
at base, sides arcuate and gradually narrower to apex, margin not serrulate, 
surface moderately densely punctured with coarse and fine punctures, basal 
impressions moderately deep. Elytra nearly black, with a yellow oblique 
spot at the humeri, and a transverse fascia at apical third, not attaining the 
suture nor margin, surface with stria? of small sub-quadrate punctures not 
closely placed, intervals flat, irregularly biseriately punctulate. Body be- 
neath and legs brownish, presternum nearly smooth, abdomen finely but 
not densely punctulate. Length .16 inch ; 4 mm. 

This species is of the same general form as punctatus but smaller. The 
elytra! markings in the two species are of the same type but in the pres- 
ent the yellow color is less extended. The antenna? are not longer than 
the head and thorax. The abdomen of the male is simple, the first joint of 
the anterior tarsi slender and moderately long. 

Two specimens, Lake Tahoe, California, Crotch. 

30. Mycetophagus tenuifasciatus Horn, n. sp. Oval, piceous 
black, feebly shining, sparsely pubescent. Head moderately densely punc- 
tate. Antenna? piceous, last three joints broader. Thorax transverse, sides 
arcuate, margin not denticulate, base very slightly narrowed, disc densely 
punctured with coarse and fine punctures intermixed, those toward the sides 
coarse, basal impressions feeble. Elytra with stria? of moderate punctures 
rather closely placed, intervals finely biseriately punctulate. Abdomen 



1S78.1 vOo [LeConte. 

finely punctulate, sparsely at middle, more densely at the sides. Legs 
nearly black. Length .20 inch ; 5 mm. 

In addition to the short black pubescence clothing the elytra there are very 
narrow sinuous bands of grayish pubescence, the first at basal third, the 
second behind the middle, and also an apical spot. The median band di- 
vides near Hie middle of each elytra and sends one branch forward, another 
backward to the margin. When the pubescence of the bands is removed 
the surface beneath is somewhat paler. 

The punctuation of the surface of the thorax varies somewhat. In a 
specimen from Marquette, Mich., the entire surface of the thorax is as 
coarsely punctured as at the sides, and the elytral sculpture also stronger. 

In addition to the anterior tarsi being three-jointed, the male has a tuft 
of silken hairs arising from an arcuate line at the middle of the first ventral 
segment. 

Occurs from the White Mountains of New Hampshire to 
Michigan, Colorado and British Columbia. 

31. M. confusus Horn, n. sp. 

Oval, piceous, sparsely pubescent, elytra maculate with yellow. Head 
densely punctured. Antennae as long as head and thorax, outer four 
joints stouter. Thorax transverse, arcuately narrowed from base to apex, 
surface densely and coarsely punctured, basal impressions moderately 
deep, margin not serrulate. Elytra densely punctulate with a feebly striate 
arrangement at middle near the base, color piceous, maculate with large 
yellow spots as in fiexuosus, the posterior band, however, not attaining the 
apex. Body beneath and legs rufo-piceous, prosternum sparsely punctate, 
abdomen densely punctate. Length .18 inch ; 4.5 mm. 

One 9 specimen, Colorado, Morrison. 

32. Diplocoelus angusticollis Horn, n. sp. Oblong-oval, piceous, 
moderately shining, sparsely pubescent. Head coarsely and moderately 
densely punctured. Thorax trapezoidal, narrowed in front, sides very 
feebly arcuate, hind angles suddenly broader covering the base of the ely- 
tra, surface coarsely and deeply punctured, with three feebly elevated 
lines at the sides which are less distinct in front. Elytra oblong-oval, 
with rows of coarse closely placed punctures, intervals with a single row 
of fine punctures, surface sparsely clothed with fine recumbent pubescence, 
with short, semi-erect, stouter hairs arising from the interstitial junctures. 
Abdomen alutaceous, sparsely punctate and finely pubescent. Length 
.13 inch ; 3.25 mm. 

This is the only species described with the thorax much narrowed in 
front. Its aspect is somewhat that of a Throscus.

three species, of which the one above described is new. 
They are as follows :

Lateral lines of thorax well marked. 

Thorax narrowed in front, sides nearly straight, hind angles prominent

Thorax not narrowed in front, sides regularly arcuate brunneus. 

Lateral lines of thorax obsolete rudis. 

D. brunneus Lee, New species, 1863, p. 73, has the thorax equally 
wide at apex and base, and the lines at the sides of the thorax well marked. 
The elytra are slightly wider than the thorax and very sparsely clothed 
with a recumbent pubescence, the interstitial punctures bearing short semi- 
erect hairs. Length .14 inch ; 3.5 mm. 

Occurs from Pennsylvania to Illinois.

A much smaller species than either of the preceding, resembling at first 
glance a Philothermus. The thorax is rather broader than the elytra, 
coarsely and densely punctured, with a feeble trace of one of the lines only. 
The surface is pubescent as in brunneus. Length .08 inch ; 2 mm. 

In describing this species Mr. Reitter says the intervals are 
without fine punctures. They are nearly obsolete in some 
specimens but quite distinct in others.

Under this name a species is described by Mr. Reitter, who 
is in doubt whether it came from "Amer. occ." or the West 
India Islands. It seems to be Mexican.

The form, color and sculpture resemble the preceding species. The pu- 
bescence of the elytra is rather more evident while the seriated hairs are 
rather less distinct. The color of the elytra is piceous with yellow spots, 
as follows : one humeral, another post-scutellar, often united, a transverse 
band behind the middle angulated in front at the middle of each elytra. 
Length 2-2.75 mm. ; .08-. 11 inch. 

The terminal joint of the antennas is broader than the preceding, trun- 
cate at tip, and nearly as long as the ninth and tenth together. 

Occurs from Missouri to Colorado, Arizona and California.

Oval, moderately convex, piceous, shining, sparsely pubescent. Anten- 
nae with club rather loose, three-jointed, the last joint a little longer and 
broader than the preceding, and truncate at tip. Thorax less coarsely 
punctured than the elytra, intervals between the punctures alutaceous, basal 
impressions absent, basal margin rather suddenly sinuate on each side of 
the middle. Elytra rather coarsely and sparsely punctate, punctures 
vaguely arranged in rows, surface shining, color piceous, with two yellow 
spots on each side, one slightly in front of middle, the other larger, one- 
third from apex, hairs all semi-erect and in distinct rows. Length 2 mm.;

Similar in form, color and sculpture to the preceding, and differing as 
follows : 

Club of antennae rather compact, three-jointed, the eighth joint, however, 
slightly wider than the seventh, terminal joint oval, not as wide as the 
preceding. Thorax rather coarsely punctate, not alutaceous, basal im- 
pressions wanting, basal margin squarely truncate. Elytra coarsely and 
moderately truncate, punctures not in stria?, pubescence partly erect not 
striate, color piceous, shining, each elytra with an oblique humeral yellow 
spot, another slightly behind the middle and also oblique, extending from 
the margin to the suture. Length 2.25 mm. ; .09 inch. 

The yellow markings vary somewhat in extent. 

Occurs from Pennsylvania to Florida.

striate, the color is usually testaceous, with a piceous dentate band behind 
the middle, another one-third from apex. Length 1.5-2 mm. ; .06-08 inch . 

This is our smallest species. It is usually of much paler color than the 
others, and the elytral markings are sometimes reduced to scattered piceous 
spots.

Marquette, Lake Superior. The punctures of the entire 
surface are coarser than in any other of our species. It must 
be considered the intermediate form between those with the 
long and those with the broad thorax. 

34. Peel i loplioriis siibcamis. Longer-oval, convex, rounded be- 
hind, obliquely narrowed in front of the elytra, black, irregularly mot- 
tled with very short gray pubescence like hoar frost, and thinly clothed 
with short erect black bristles. Beneath finely, densely punctured, finely 
pubescent, legs piceous ; tarsi paler, fourth joint with a long lobe. 
Length 4.4 mm ; .17 inch. 

Escanaba, Lake Superior. In form and pubescence this 
species resemembles Byrrhus^ but the tarsal lobe requires its 
reference to the present genus, with which it also agrees in 
having the mandibles not covered by the prosternum in re- 
pose. 

35. Paromalus teres. Cylindrical, but not slender, shining black ; 
head and prothorax punctulate, elytra finely not densely punctured, each 
with faint traces of two oblique striae near the base ; sutural stria want- 
ing. Pygidium very finely punctulate, under surface finely and sparsely 
punctured ; mesosternum emarginate in front, marked with a fine lateral 
line; prosternum flattened without striee. Length 2 mm ; .08 inch. 

Sault St. Marie ; one specimen. This species only differs 
from P. seminulum by the cylindrical form, in which it de- 
ceptively resembles Teretrius americanus; by having the ely- 
tra more finely punctured, and by the entire absence of the 
sutural stria. 

The following species may be conveniently described on 
the present occasion.

same form as H. brunneipennis, sparsely pilose with long slender sub -erect 
yellowish hairs. Head opaque, finely punctulate, broadly concave. Pro- 
thorax with the sides slightly nicked at the middle, lateral lobes of the 
disc obsoletely punctulate, divided behind the middle by a transverse 
groove, hinder part deeply margined on both sides ; the impressed groove 
separating the lateral lobe from the disc is much deeper and broader at 
the base. Elytra with three very fine striae, the inner one effaced behind 
the middle. Pygidium opaque, very finely and densely punctulate. Pros- 
ternum narrow, flat, densely punctulate, lateral edges well defined. Length

Head finely scabrous, with an obsolete transverse impressed line ; epistoma 
very finely margined, sub-truncate. Prothorax scarcely wider than long, 
sub-quadrate, sides very slightly rounded, fringed with stiff hairs, serrate 
towards the base, which is broadly rounded and distinctly margined ; front 
angles prominent, hind angles rounded, disc coarsely sparsely punc- 
tured with some fine punctures intermixed. Elytral striae deep, distinctly 
punctured, interspaces smooth. Scutellum small, smooth. Front tibiae 
with three large teeth, middle and hind tibiae gradually but moderately di- 
lated, transverse ridges short ; spurs of hind tibiae long, hind tarsi two- 
thirds as long as the tibiae. Length 4.5 mm ; .175 inch. 

Marquette, Lake Superior, two specimens ; California, 
( precise locality unknown, probably from the Sierra Nevada), 
one example. The humeri in one Lake Superior specimen 
are prominent and tnberculate, in the other two rounded ; 
in the former the spurs of the hind tibiae, though not longer, 
are more slender than in the two with simple humeri. These 
differences are probably sexual, but cannot be fully investi- 
gated without more specimens. 

For the easy recognition of our species of this genus I

Soc, 1871, 293), as follows:

less slender than P. reticulata, and is easily known by the entire 
absence of phosphorescent spots on the abdomen. I may here 
mention that a 9 of the last named species in the collection 



LeConte.] VlZ [April 18, 

of Dr. Horn has short elytra, much as in the 9 of Photinas 
(Gynaptera) scintillans. This insect has a very strong resem- 
blance to Lamprohiza splendidula of Europe, but is generi- 
cally distinct by the longer antennae, and by the small acicu- 
lar twelfth joint of those organs. Specifically, it differs by the 
disc of the prothorax being smooth, the transparent spots 
more oval, not curved, and by the hind angles of the pro- 
thorax being greatly retracted. 

Hadrobregmus linearis Lee. Pr. Ac. Nat. Sc. Phila. 1865, 232. 

A very singular series of this insect was collected at Detroit. In two in- 
dividuals, both antennoe have ten joints, that is to say there are five small 
joints between the rounded second joint and the first of the elongated joints. 
In one specimen the right antenna? has eleven, while the left has ten joints ; 
this difference is produced by the division of the fourth joint into two 
parts. In another specimen the right antenna has ten, while the left has 
but nine joints ; and it is again the fourth joint of the left that is divided, so 
as to form the fourth and fifth of the right, the distal part resulting from 
this division, or the fifth joint of the eleven -jointed antenna, is even a little 
wider than the fourth joint. It is thus apparent, that in this type of the 
Serricorn series, the increase of number of joints from nine to eleven is 
produced by a power of segmentation, or vegetative repetition residing in 
the fourth joint of the antenna. 

Another inference from this series of specimens is that the nominal spe- 
cies of this genus may have been unduly multiplied, and that they must 
be denned b} T other than antennal characters. A renewed examination of 
the specimens in my collection, indicates that all the species recognized by 
me in the memoir above cited are valid, and easily distinguished by the 
characters there given. 

41. Xyletinus lugubris. Oval, convex, blackish, piceous, dull 
with very fine dense punctuation, and very short pruinose pubescence. 
Prothorax more than twice as wide as its length, very convex, declivous 
near the base, narrowed in front, sides rounded, incurved near the base

Marquette, Lake Superior. Found also in Massachusetts 
and Nebraska. This species is allied to X. fucatus, but is 
smaller and less robust, and easily known by the prothorax 
more convex transversely and more declivous towards the 
base. 

Several specimens of X. fucatus were collected by Mr. 
Crotch at Calaveras, California, which only differ from those 
found at Lake Superior by the smaller size, darker color and

less deep elytral stride. The following species seems to differ 
by the much coarser pubescence, and by the sides of the pro- 
thorax not at all flattened. 

42. Xyletinus piibescens. Oval, convex, piceous, opaque, with 
tine rugose punctuation, densely closed with rather coarse yellowish pubes- 
cence. Prothorax more than twice as wide as long, narrowed in front, 
rounded at the sides, which are not at all flattened, transversely convex, 
slightly declivous towards the base. Elytra with deep impunctured striae, 
scutellar stria long, interspaces flat. Beneath densely punctulate and pu- 
bescent, Length 2.S mm. ; .11 inch. 

Bosque Co., Texas ; one specimen ; Mr. GJ-. W. Belfrage. 

MICROMAI/THUS n. g. Lymexylid^e? 

Body elongate, head wide, with rounded, convex eyes ; prothorax wider 
than long, narrowed behind, elytra a little shorter than the abdomen, sub- 
striate, smooth at the apex ; resembling in miniature a narrow Hydnocera, 
but greatly differing by the antennae, palpi and tarsi. 

Antennae shorter than the head and prothorax ; 1st and 2d joints round- 
ed, as wide as long ; 3d small, 4-10th wider, and becoming gradually 
transverse, 11th oval, not wider than the 10th ; inserted on the edge of the 
front, before the eyes, which are convex, prominent, rounded, not emar- 
ginate, and rather finely granulated. Maxillary palpi with the last joint 
moderately large, oval, pointed ; labial similar but much smaller ; gular 
sutures straight, widely separated. Prothorax transverse, without angles, 
narrowed behind, not margined on the sides. Legs rather long, slender, 
tibiae without spurs, tarsi 5-jointed, as long as the tibiae, joints 1-4 
equal, not lobed. 5th as long as the others united, claws simple. Front 
coxae, oblique, conical, prominent, contiguous at the apex ; middle coxae 
large, oblique, conical, not continuous, hind coxae transverse, conical, promi- 
nent. Abdomen with six free and nearly equal ventral segments. Pros- 
ternal sutures not visible ; side pieces of metathorax long and narrow. 

No sexual difference can be observed in any of the specimens collected, 
two small spiculae project from the tip of the abdomen in each of them. 

43. M. delbilis. Piceous, shining, antennae, palpi and legs yellow, head 
smooth, front transversely depressed. Prothorax smooth, with a faint 
transverse impression. Elytra feebly scabrous, nearly smooth at the tip, 
striate except at base and tip. Beneath punctulate, slightly pubescent ; two 
or three dorsal segments exposed. Length 2.2 mm.; .85 inch. 

Detroit, in decomposing wood, August. I have referred 
this genus to Lymexylidee on account of the resem- 
blance of the antennae and coxse to those of Hylecoetus. In 
such a feeble and ill-developed form we should naturally ex- 
pect the peculiar sexual characters seen in the palpi of the 
other genera to disappear.

44. Phymatodesmaculicollis. Blackish, piceous, finely sparsely 
pubescent, Head and protliorax finely not densety punctured, the latter a 
little wider than long, rounded at the sides, rufous, with a broad black 
dorsal stripe. Elytra not wider than the protliorax, densely punctured. 
Beneath sparsely punctulate, protliorax rufous, legs piceous, coxse and 
thighs (except at base) blackish. Front coxae contiguous ; mesosternum 
triangular, middle coxse slightly separated. Antennas slender, filiform, a 
little more than half as long as the body, 4th joint equal to 5th. Length 
6.3 mm. ; .25 inch. 

Isle Royale, Lake Superior; but one specimen found. 

45. Typocerus spars us. Black, shining, pubescent with coarse 
black hair. Head rather finely punctured. Protliorax sparsely and coarsely 
punctured, margined at base and apex with golden hair. Elytra sparsely 
and coarsely punctured, punctures becoming finer towards the tips, which 
are dehiscent by the curvature of the suture ; bidentate, the outer tooth 
longer than the sutural one; ornamented with a transverse yellow spot very 
near the base, and three transverse yellow bands extending from the side 
margin to the suture. Beneath punctulate, pubescent with yellowish gray 
hair. Antenna? ( 9 ) two-thirds as long as the body, not serrate, sixth and 
following joints with an elongate depressed sensitive space, extending from 
base to tip or nearly so. Length 10 mm. ; .40 inch. 

Escanaba, Lake Superior. This species resembles in ap- 
pearance T. zebratus, but is at once recognized by the sparse 
punctuation of the protliorax and elytra. 

46. Chlamys cribripeimis. Sub-quadrate, coppery bronze, of the 
same form and color as G. assimilis, from which it differs by the protliorax 
more shining, finely strigose, impunctured, with the dorsal elevation only 
obsoletely divided at the highest part. The elytra have the elevations simi- 
larly placed, but smaller, and the interspaces are very coarsely, but not 
densely punctured. The pygidium is less opaque, in fact, somewhat 
shining, and more deeply punctured, and without the shallow rounded im- 
pressions seen in that species. Antenna? fulvous, labrum black. Length 2.5 
mm.; .10 inch. 

Detroit ; one specimen. 

47. Pliyllotreta rolbusta. Less elongate than usual, black with a 
greenish bronze lustre. Head punctured, vertex with a short, fine, longitu- 
dinal impressed line. Protliorax twice as wide as long, strongly punctured, 
slightly narrowed in front, sides rounded, base truncate, not margined. 
Elytra oval, wider than the protliorax, rounded on the sides, similarly 
punctured ; pale yellow, with a wide sutural stripe narrowed near the 
base, and rounded behind at about one-fifth from the tip, wmere it ends ; 
the side margin is blackish from the base nearly to the tip, and the color is 
a little wider about the middle ; there are besides two spots on each etytron, 
one occupying the humeral callus, and attaining both the base and side

though separate from it. Antennae slender, more than one-half as long as 
the body, black, first three joints brown. Beneath black, tibiffi and tarsi 
piceo-testaceous. Length 2 mm.; .08 inch. 

Detroit ; one specimen. Quite different from any other 
striped species in our fauna, and representing the European 
P. bi guttata Foudras. Alt. 251. 

The adoption of the Kirbyan name Orchestris for this genus by Mr. 
Crotch (Proc. Ac. Nat. Sc. Phila. 1873, 65) in preference to Pliyllotreta 
Foudras, seems to me inexpedient for the following reasons : 

Kirby (Faun. Proc. Am. IV, 217), characterizes a sub-genus Orchestris 
by a very brief formula, which is applicable to several groups of the old 
genus Haltica, to which generic names are now affixed. 

His sub-genus was evidently defined for the purpose of describing two 
striped species of large size now enrolled in Disonycha Chevr., but in order 
to make his volume (exclusively devoted to North American species), more 
intelligible to the English student, he casually observes that his sub-genus 
corresponds with section b. l,*ff, of Stephens, "of which H. Nemorum is 
the type. ' ' 

Now while unwilling to dispute that H. nemorum is the type of Stephens' 
unnamed British group, it is quite apparent that the remark of Mr. Kirby 
indicates simply an error of judgment or observation in not perceiving the 
differences (if there be any), between his large American species, for which 
the sub-genus was established, and the small European species; and thus 
the sub-generic name belongs properly to the former group. 

The name Orchestris, therefore, unless it is dropped entirely in conse- 
quence of its heterogeneous limitation, can be used only to supplant Bis- 
onycha Chevr. (1844), and the present group must be known as Phyllo- 
treta, under which name it was first characterized by Foudras in 1860 

48. Cliaetocnema rudis. Oval, convex, bronzed, not shining. 
Head finely punctured. Prothorax rather densely and stronghy punctured, 
very little narrowed in front, sides slightly rounded, finely margined, base 
not margined. Elytra with rows of deep punctures, the inner ones slightly 
confused near the base ; space between the scutellar stria and the suture 
irregularly punctured. Beneath punctured, tibiae and tarsi brown. Length 
1.8 mm.; .07 inch 

Marquette, Lake Superior ; one specimen. This species be- 
longs in the table (ante. p. 419), after cribrata, from which 
it differs by the much less confused elytral strise. 

49. Mycetocliares gracilis. Elongate, piceous-black, shining, 
finely and sparsely pubescent. Head punctured, front depressed, vaguely 
foveate. Antennas nearly half as long as the body, piceous, base brown ; 
2d joint small, 3d a little longer than the 4th. Eyes convex, prominent. 
Prothorax wider than the head, wider than long, narrowed and much

rounded on the sides in front ; strongly punctured, disc broadly longitudi- 
nally impressed behind, flattened and explanate at the hind angles, which 
are rectangular ; impressed each side at the base, which is truncate and 
not margined. Elytra a little wider than the prothorax, parallel, striae 
punctured, scarcely impressed ; interspaces transversely sparsely rugose 
and finely punctured. Beneath shining, trunk finely punctured. Ab- 
domen sparsely punctulate. Front coxae separated by the prosternum, 
vhich is narrow and punctured. Length 5.5 mm. ; .22 inch. 

Marquette, Lake Superior ; one specimen. This species is 
^elated to M. bicolor, but is quite different in the less deeply 
striate elytra, the more strongly punctured prothorax and 
the dark antennae and legs. 

For the pupose of more clearly defining several new species, 
my table (New Sp. Col. Smiths. 8vo., 138) may be expanded 
as follows :

In the Munich Catalogue Mycetophila G-yll. (1810), which antedates My- 
cetor hares Latr. (1825), is adopted for this genus ; the former name was, 
however, preoccupied by Meigen (1803), for a genus of Diptera, as is very 
properly mentioned by Lacordaire (Gen. Col. V., 507, note). 

M, basillaris (Say) remains unknown. When found, it will be easily 
recognized by the scarcely punctured prothorax, with three posterior im- 
pressions, and the striate elytra having an oblique red spot like the species 
3-5 of the table. 

50. Mycetochares piibipeunis. Dark brown, shining, rather 
densely clothed, especially on the elytra, with long brown pubescence. 
Head punctured, eyes more transverse and less prominent than in the other 
species; antennae paler brown, rather stout, about half as long as the body. 
Prothorax one-half wider than long, scarcely narrowed in front, not dense- 
ly nor strongly punctured, broadly longitudinally impressed at the middle 
of the base, and obliquely near the hind angles; sides moderately rounded, 
not explanate, base not margined . Elytra not wider than the prothorax, 
punctured ; striae punctured not impressed, nearly obliterated at the sides 
and behind. Beneath punctulate and finely pubescent, legs piceo-rufous ; 
prosternum extremely narrow between the front coxse. Length 4. 8 mm. ; 
.19 inch. 

California, at Tejon and San Diego. Easily known by the 
more transverse and scarcely prominent eyes, and very nar- 
row prosternum. 

51. Jtfycetocliares laticollis. Elongate-oval, not convex, above 
olack, shining, elytra each with an oblique red spot near the base ; sparsely 
pubescent. Head and prothorax sparsely punctulate, the latter fully twice 
as wide as long, widest at the middle, very much rounded on the sides, 
which are slightly explanate near the hind angles ; base extremely finely 
margined, with three broad shallow impressions, of which the middle one 
is nearly obsolete. Elytra a little narrower than the prothorax, not densely 
punctured, with very faint traces of strioe near the suture. Antennas rather 
stout, under surface and legs testaceous -red ; palpi and large gular spot 
yellow. Length 6.3 mm.; .25 inch.

59. Proc torus armatus Lee. Khynch. 212. 

Several, specimens of this curious insect were found at 
Marquette, and among them are dV in which the two pro- 
cesses of the apical edge of the last ventral segment are very 
short, and scarcely apparent, though the anterior tubercle or 
spine and the large excavation are as well developed as in 
the other specimens.

separated Encalus from Proctorus, are only sexual ; and the 
peculiar ventral armature of the ^ shows that they consti- 
tute but one genus. 

61. Orcliestes canus Horn* n. sp. Black, sparsely clothed with 
grayish pubescence. Antennae testaceous, funicle six-jointed. Thorax 
broader than long, apex one -third narrower than base, sides arcuate, disc 
coarsely punctured. Elytra oval, gradually narrowed posteriorly, disc con- 
vex, deeply and rather broadly striate, striae with coarse, deep and closely 
placed punctures, intervals irregularly biseriateh" punctured, the punc- 
tures bearing short grayish hairs. Body beneath and legs black. Length 
3 mm.; .12 inch. 

The posterior femora are strongly thickened. This species cannot be con- 
founded with any other than pallicomis, from which the deeply striate 
elytra, and very evident grayish pubescence will distinguish it. 

Specimens are before me from Isle Roy ale and Escanaba, 
Michigan, and from San Juan, Colorado. 

62. Orcliestes minutus Horn, n. sp. Black, sparsely clothed with 
grayish pubescence. Antennae piceous, scape and first joint of funicle paler, 
the funicle 6-jointed. Thorax broader than long, apex scarcely narrower 
than base, sides arcuate, surface coarsely punctured. Elytra oval, broadest 
at middle, disc slightly flattened, deeply striate, striae with indistinct dis- 
tant punctures, intervals wrinkled, irregularly, finely, biseriately punctu- 
late. Body beneath and legs black. Posterior femora feebly thickened. 
Length 2 mm. ; .08 inch. 

This species resembles rufipes, but is somewhat smaller, disc of elytra 
flatter and with entirely black legs, and with the thorax much more arcuate 
at middle.

centrically for one-third its length ; sides and posterior part, strongly, rather 
densely punctured, with a narrow smooth median space. Elytra with ap- 
proximate rows of punctures, interspaces irregularly transversely rugose ; 
apical declivity refuse and crenate, deeply concave near the suture, which 
is elevated and also crenate. Length 1.6 mm. ; .06 inch. 

(j\ Head broadly concave and opaque, fringed with long yellow hair. 

9 . Head slightly convex, strongly punctured. 

Marquette, Lake Superior. Related to the two preceding, 
agreeing with P. annectens in sexual characters, but with the 
crenations of the apical declivity of the elytra stronger than 
in P. consimilis, while the form is a little more robust than 
in either. 

69. Pityoplitliorus pusio. Cylindrical, shining, piceous, with a few 
erect yellow hairs behind the middle of the elytra. Prothorax not longer than 
wide, roughened in front almost to the middle, strongly and densely punc- 
tured at the sides and behind, with a large, smooth, well-defined dorsal space. 
Elytra with small punctures, arranged in tolerably regular rows, apical 
declivity hroaclly concave, slightly refuse each side, with about three veiy 
small teeth ; suture elevated, also with three or four slight inequalities. 
Front tibise with two very faint small teeth. Length 1.6 mm.; .06 inch. 

Marquette, Lake Superior ; one specimen. The head is re- 
tracted so that the front cannot be seen. This species is of 
the size and form of P. pulicarius, but the elytral sculpture 
and the apical declivity are quite different ; it is more nearly 
related to the Californian P. puncticollis, but differs by the 
more robust form, and by the sparse crenations of the apical 
declivity, which are wanting in that species. 

70. Pityoplitliorus opaculus. Cylindrical, slender, testaceous, 
head and disc of prothorax darker ; anterior half rather strongly asperate, 
sides and posterior half sub-rugosely punctulate, dorsal line smooth, narrow. 
Elytra finely alutaceous, nearly opaque, marked with scarcely perceptible 
distant strise of very fine punctures ; apical declivity neither refuse nor con- 
cave, suture elevated, limited by a distinct striae. Length 1.3 mm.; .05 inch. 

Marquette ; one specimen. This species must be placed 
after P. comatus in my table (Rhynch. 352). The head is punc- 
tured, and slightly convex, the legs and antennae are yellow.

Marquette ; not rare. The club is transversely annulated, 
and it therefore belongs to Pityophthorus ; the sexual differ- 
ences indicate that Xyleborus hamatus Lee, Am. Ent. Soc. 
1874, 72, is the 9 of carinulatus Lee. ibid. {Pityophthorus car. 
Lee, Rhynch. 352). 

TO. Pityoplitliorussparsus. Xyleborus sparsusltec, Tr. Am. Ent. 
Soc. 1868, 160. 

Marquette, Lake Superior ; rare. This species, as is shown 
by the examination of well preserved specimens, has the club 
transversely annulated, and therefore belongs to Pityophthorus. 
There seems to be no sexual differences in the declivity of 
the elytra, but the J has the head fringed with very long- 
hair. 

73. Xyleliorus puiictipeiuiis. Slender, cylindrical, piceous, 
shining, thinly clothed with long erect yellow hair, granulato-asperate for 
more than one-half the length, sides and behind densely and coarsely punc- 
tured ; smooth median line rather wide, very distinct. Elytra coarsely 
punctured, though not in altogether regular rows, suture elevated, and su- 
tural stria deep for the whole length : declivity oblique, retuse, concave 
part coarsely punctured ; there are two acute dis oidal cusps, and several 
small indistinct marginal ones, the most anterior of which is near the su- 
ture and more prominent. Front tibiae moderately dilated, bidentate. 
Length 2.5 mm.; 10 inch. 

Marquette, Lake Superior; one ? specimen. This species 
might be easily confounded with Pityophthorus sparsus, but 
on comparison the difference in the antennal club is quite 
obvious ; in the present case it is thicker, and obliquely 
truncate at tip, so that the proximal half at least is smooth 
and shining, and limited by a curved line. The punctures of 
the prothorax and elytra are coarser and more numerous, and 
the apical declivity is also punctured. 

74. Xylocleptes decipiens. Slender, cylindrical, brown, shining. 
sparsely clothed with erect yellow hairs ; antenna? and legs yellow. Pro- 
thorax longer than wide, slightly asperate in front with transverse rugosi- 
ties ; sides and behind coarsely but not densely punctured ; median line 
and a smooth space each side well defined. Elytra <$ coarsely punctured, 
punctures not arranged in rows ; declivity nearly perpendicular, scarcely 
retuse, slightly impressed along the suture, which is feebly elevated. Head 
convex, finely punctured ; front tibiae moderately dilated, serrate with four 
or five very small teeth. Length 1.3 mm. ; .05 inch. 

Detroit; one specimen. This species greatly resembles in 
sculpture Pityophthorus puliearius,hut is more slender, and the 



U-O [LeConte. 

antenna! club is very different; the sutures are long curves, 
concentric with the apical margin, and the first joint is gla- 
brous, shining and elliptical in form. 

To this genus should be referred the Alaskan Bostrichus 
concinnus Mannh. Bull. Mosc. 1352, 358 ; Tomicus cone. Lee, 
Tr. Am. Ent. Soc. 1868, 164 ; Rhynch. 367. Only 9 9 have 
thus far been collected. 

75. Tomicus ba Isa mens. Blackish piceous, or brown, cylindrical, 
shining, clothed with long erect yellow hairs. Prothorax longer than 
wide, asperate for about one-half the length, then strongly but not very 
densely punctured at the sides and behind ; median space smooth, narrow, 
badly defined. Elytra with striae composed of large rather distant punc- 
tures, interspaces with equally large but very distant punctures ; declivity 
concave, sparsely not deeply punctured, margin with several small teeth 
and two large ones ; the apical part of the margin is not a continuous ridge. 
Front tibiae dilated, with fourdistinct teeth. Length 2.3 mm. ; .09 inch. 

tf Head flat, shining, hairy with very long } r ellow hairs ; the four larger 
teeth of the apical declivity less prominent. 

9 Head finely punctured ; carinate with an acute elevated line ; four 
larger teeth of apical declivity very prominent. 

Central New York, where it has seriously injured the 
forests of Abies balsamea. For an account of the ravages of 
this insect see the Report of the Botanist in the 28th An- 
nual "Report of the New York State Museum of Natural 
History, 1874, p. 32-38. I am indebted to Mr. J. A. Lintner, 
of the State Museum, at Albany, for a series of speci- 
mens. Some care will be necessary to distinguish this in- 
sect from Xyleborus punctipennis, but apart from the differ- 
ences of theanntenal club, the prothorax of T. balsameusis less 
densely punctured, the strise are more distinctly formed, and 
the apical declivity is less punctured, with the teeth (9) 
more prominent, and not distinctly separated from the ele- 
vation of the margin of the declivity. The front tibiae are 
more distinctly toothed. The sutures of the club are straight 
and transverse, so that it belongs to the division Orthotomicus 
Ferrari, and may be placed in the table (Rhynch. 363), after 
latidens, to which it has no resemblance. 

7G. Micracis opaciollis. Slender, cylindrical, dirty testaceous. 
Prothorax darker, opaque, finely asperate in front, indistinctly punctulate, 
thinly sprinkled with very small ochreous scales. Elytra shining, punc-

tured in rows, interspaces with rows of very short stout bristles. Eyes 
extending to the under surface of the head, not widely but distinctly sep- 
arated beneath. Club of antennae with broadly curved sutures. Length 
1.7 mm. ; .07 inch. 

cf. Scape of antennas fringed with very long hair; (front not visible, 
the head being retracted). 

Detroit ; one specimen. To be placed in the table, (Khynch. 
368), before M. rudis. 

77. Micracis asperulus. Slender, cylindrical, black, entirely 
opaque. Head not concave, scarcely punctured. Prothorax more strongly 
asperate in front than in the preceding, scarcely punctured behind, sprin- 
kled with small yellowish scale-like hairs. Elytra obsoletely striate, 
densely rugosely punctured, interspaces with rows of very short stout 
bristles as in 31. opacicollis. Eyes very narrowly separated beneath. An- 
tennae ferruginous, club with broadly curved sutures. Legs ferruginous. 
Length 1.7 mm. ; .07 inch. 

<j\ Scape of antennas fringed with very long hair. 

Detroit ; in dead oak twigs. Of the same size and form as 
the preceding, but quite different in sculpture. 

78. Scolytus unispiiiosus / < Rhynch. 372. 

Marquette, Lake Superior ; one specimen. This differs 
from the two specimens from Oregon upon which the species 
was established, by the punctures of the elytra being not so 
small, and by the spine of the first ventral segment being 
much less developed, becoming in fact a small tubercle ; the 
elytra are fringed with brown. I consider none of these as 
specific characters. 

79. Scolytus rugulosus Ratzeburg, Ins i, 230; pi. x f. 10. 
This is a suitable opportunity to notice the introduction 

of this European species into the United States. I have re- 
ceived specimens from Elmira, N". Y., where it attacks peach 
trees. According to Ratzeburg it is rare inGTermany, but is 
found upon plum and apple trees. 

80. Choragus Harrisii. Elongate-oval, sub-cylindrical, blackish- 
brown, shining, finely pubescent. Prothorax finely less densely punc- 
tured, not opaque ; elytra with deep coarsely punctured striae, interspaces 
not wider than the striae, scarcely punctulate. Length 1.2 mm. ; .05 inch. 

Detroit ; August ; one specimen. Differs from our other 
two species by being more distinctly (though very finely) 
pubescent and by neither the prothorax nor elytra being 
opaque.

4. Description of the Larva of Micromalthus debilis Lee. 
By H. G. Hubbakd. 

Color transparent white, mandibles and anal appendage castaneons. 

Form cylindrical, very slightly flattened beneath, hardly narrowed lat- 
erally in front and behind. Body glabrous, except a few hardly visible 
hairs upon the sides, without legs. Length 0.10-.12 inch.; width about 
0.03 inches. 

Head not quite as broad as the segments of the abdomen, convex, trans- 
verse, enlarged posteriorly; sides rounded, convex ; anterior border nearly 
straight, posterior border emarginate ; above and below a few long bristles. 
No ocelli. 

Antennas short, inserted in depressions on the anterior angles of the 
head, of four joints increasing in length, the first very short, transverse, 
the second smaller, about as long as broad, the third longer than the pre- 
ceding, with a short oval lobe below, before the tip, the fourth twice as 
long as the third, slender, blade-shaped, tipped with a minute spine. 

Labmm transverse, somewhat enlarged anteriorly, borders nearly 
straight, anterior angles rounded, with long stout spines above and below. 
Mandibles as long as the antennae, stout, carved, three-toothed with a large 
hatchet-shaped basal lobe, oblicpaely ridged upon the under surface. 

Maxillse, very large and prominent, longer than the mandibles ; with 
palpi of three joints, the first and second short, C3 r lindrical, the third as 
long as the first and second united, more slender, flat, and divided nearly 
to the base into two superimposed lobes bearing papillae ; maxillary lobe 



1878.] ^67 [Hubbard. 

divided anteriorly by a deep notch into two portions, the apical, smaller 
and narrower than the basal, blade-shaped, tipped with a long slender spine, 
and bearing four long and stout teeth projecting at right angles to the lobe, 
like the blades of a half-opened penknife ; the basal portion with two rows 
of teeth on the border, and a slender tooth and bristle at the apex. 

Labium consisting firstly, of an elongated, triangular mentum, with the 
apex thickened in a conical protuberance, bearing a pair of bristles near the 
middle, and another pair upon the thickened tip ; secondly, of a transverse 
palpiger, bearing small fleshy palpi of two subequal joints, and its anterior 
border prolonged between them in a conical projection ; thirdly, of an 
elongated, convex, corneous ligula, enlarged anteriorly, with straight 
borders and a pair of bristles near the tip. Behind and above the mentum 
and plainly seen through the transparent tissues, is a broadly triangular, 
horny piece, the base of which extends between the hinges of the mandi- 
bles, and the apex reaches as far as the middle of the ligula ; upon the 
upper surface oblique grooves on each side correspond with the ridges 
upon the basal lobes of. the mandibles, into which they lock when the man- 
dibles are closed.* 

Thoracic segments slightly thicker than the abdomen, the first longer, 
the two following subequal in length. 

Abdomen cylindrical or slightly depressed, of nine segments, the first 
eight subequal, transverse, each with a few long bristles, the ninth conical, 
scatteringly covered with long bristles, terminating abruptly in two minute 
toothM appendages, one proceeding from the dorsal surface, and arching 
downwards, the other from the ventral surface, curving upwards, and re- 
sembling two hands with partly extended fingers, having the palms 
turned towards each other. The upper and longer appendage appears to 
be tubular for one-third of its length from the base, the remainder is con- 
cave beneath, and terminates in two terminal and six lateral teeth, directed 
downwards, their bases forming longitudinal ridges on the concave under 
surface. The lower appendage is shorter, more strongly curved, and in the 
opposite direction, concave above, expanded into a palm at the end, with 
eight leeth as in the preceding; the concave upper surface is distinctly 
denticulate. 

Tbe larva lives in damp situations, in the soft, crumbling wood of old 
oak logs, which have become entirely disintegrated and colored dark red, 
probably by a microscopic fungus. A number of larvae, pupae, and images 
were found together in a small portion of such a log on August 17th, 1874, 
at Detroit, Michigan. 

As Dr. LeConte has placed this insect in the family Lymexylida?, it will 
be interesting to compare its larva with that of Hylecwtus lugubris Say, 
specimens of which are before me. The larvae of Hylecoztus were taken 
from cylindrical burrows in the solid wood of the American linden. It 

*This piece and tbe mandibles, the forms and relative positions of which are 
shown in fig. 9 of the plate, though very conspicuous in dissections under the 
microscope, are omitted in fig. 5 in order to avoid obscuring overlying parts. 



Hubbard.] UUO [April 18, 

has a cylindrical body of twelve segments ; a globular head, with two 
large ocelli, which are, however, covered by the epidermis ; the first tho- 
racic segment is enlarged, and partly covers the head, like a hood ; the 
three thoracic segments bear well-developed legs ; and the abdomen termi- 
nates in a long tapering style, toothed and concave on the upper surface, 
and turning upwards at the end ; the stigmata are large and in their normal 
positions, one pair beneath, on the thorax, and eight pairs on the sides of 
the abdominal segments. 

The antenna? are four-jointed, exceedingly minute and stout, and, as in 
Micromaltlius, have the third joint lobed beneath, an apical spine, and oc- 
cupy similar positions on the anterior angles of the head ; the maxillae also 
have the lobe divided into an upper and lower portion, although the sepa- 
ration is not very distinct, and appears under the lens as a corneous line, 
the spines upon the lobe are slender and not markedly different upon the 
two portions. The labrum and labium are stout and thick, but do not pre- 
sent important structural differences from the same parts in Micromalthus. 
The mandibles are simple or slightly notched, the basal lobes not promi- 
nent, but finely ridged, and closing upon a triangular corneous piece which 
lies above the mentum. All the parts of the mouth in Hylecoztus are 
smaller, stouter, and simpler in their structural details than the correspond- 
ing organs in Micromalthus, differences which perhaps have some relation 
to the harder material in which the former lives. Notwithstanding the 
striking difference in their external forms, the important structural analo- 
gies between the antenna; and mouth parts, seem to indicate a relationship 
between these two larval forms.
